The organs of the abdominal cavity are what every person has and invariably, day after day, ensures the normal coordinated work of the body. Unfortunately, very few people know what is the scheme or where are these or those internal organs, their departments, and what is their structure in general?

Location of the abdominal organs

The organs of the abdominal cavity include the following systems: the kidneys and adrenal glands, the gallbladder and ureter, as well as the liver, spleen and the entire gastrointestinal tract. In front and on the sides, their location is limited by the abdominal wall, which is permeated with muscles, as well as fatty tissue and connective tissue formations that are present in every person without exception, which can be seen in all the pictures.

In general, the abdominal cavity can be described as all the space that is under the diaphragm. It is in it that all organs are concentrated, and the abdominal region passes into the pelvic region. The space behind the peritoneum is characterized by the fact that it is covered with a serous membrane, which extends to all the internal organs of a person.

It should be noted that due to some physiological features, the friction of the surfaces of the internal organs against each other does not occur. A similar effect is achieved due to the presence of an epithelial cover, as well as a serous fluid that complements the structure, as can be seen in the pictures and photos. The separator of the organs that belong to the chest and abdominal cavity is the diaphragm, the location of which is always the same.

In the upper region of the peritoneum is the stomach and its departments that contain food. It is known that it is its quantity that directly affects the size of this human organ. By itself, the stomach resembles a small pouch that has a specific outlet, namely a tube, which is known as the intestine.

Certain functions are assigned to it, for example, the absorption of the main part of the nutritional components.

The presented sections of the gastrointestinal tract in any person end with an anus, which is obvious in any photo or picture. Experts point out the following features that determine the structure of this system:

1. The spleen belongs to the organs of the abdominal cavity and the space behind the peritoneum. This happens despite the fact that it belongs to the lymphatic system, but it can be detected (for example, during ultrasound) under the left hypochondrium;
2. the upper part of the abdominal region is occupied by the liver, which is attached to the diaphragm, stomach, as well as the intestines and abdominal wall through ligaments. It is she who is responsible for the formation and secretion of bile and similar components;
3. the preservation of the location of all internal organs of a person is ensured by the abdominal press. This is most relevant in a vertical position.

It should be noted that the internal organs have even more specific protection, namely that which is provided by the bones. From the back, this is the spinal column and pelvic bones, in front - exclusively muscles. There are other forms of protection that allow you to survive and cope with any extreme situations and even injuries. It should also be noted that it is possible to control how correct the structure of the internal organs of a person is, whether certain departments work correctly with the help of ultrasound. This method is 100% effective. About some differences between men and women in the structure of the internal organs of the abdominal cavity - further.

Differences in the structure of internal organs between men and women

Before moving on to the structural features of the internal organs of males and females, which are visible even in the paintings, I would like to draw attention to some other points. In particular, the fact that a characteristic feature of the structure of the peritoneal organs should be considered a covering of a very thin serous membrane. We are talking about mesothelial tissue, which has a significant amount of strong fibers.

In addition, the mesothelium ensures the production of lubrication, reduces the friction of organs - it is precisely due to this feature that characterizes the structure of a person that we do not experience painful and simply unpleasant sensations.

Such pains can manifest themselves only in diseases or inflammatory conditions, infectious lesions.

Speaking directly about the female representatives, it is necessary to pay attention to the fact that one of the main differences is the presence of tubes in the pelvic area that communicate directly with the uterus. Through the vagina, the sexual sphere gets the opportunity to communicate with the external environment, which is obvious in the pictures. It is possible to fix certain internal female organs of the reproductive system, as well as the prostate gland in men, when performing ultrasound of the human peritoneal organs, which also demonstrates some other departments.

If we talk specifically about the organs of the abdominal cavity of the male representatives, then they are located exclusively in a confined space. However, regardless of the gender of a person, the internal organs and their structure are always determined by the presence of a serous membrane. The difference lies only in whether one or another internal area is partially covered or the film is located on the entire surface part.

In general, the placement of the organs of the peritoneum and the space behind the peritoneum is possible in three ways. The first is extraperitoneal, which is characterized by the fact that the peritoneum covers the insides exclusively in front. This is characteristic of the kidneys. Further, to the second option, experts rank mesoperitoneal, within the framework of the development of which only three sides of one or another inside have a coating, and the fourth remains uncovered. The most characteristic example is the liver, which is almost completely covered with a serous membrane.

The third option is intraperitoneal, which is characterized by the fitting of the organ by the abdominal region from all sides. One example of this is the small intestine. About how exactly the diagnosis of the internal organs of a person is carried out, how their structure is determined and much more, further.

How is the abdominal cavity diagnosed?

In order to 100% accurately determine the location and any other features of the abdominal organs in men and women, it is necessary to attend to a diagnostic examination. The main technique is ultrasound, due to which, as in the pictures, it turns out to be obvious, for example, the key causes of pain in the abdomen. In addition, the state of the gallbladder, liver is assessed, the pancreas and aorta are examined.

The specialist gets the opportunity to visually verify whether the stones are in the bile ducts, whether it is possible to confirm the existing suspicion of ascites. In addition, it is the presented method of examination, as in the pictures, that reveals an organic lesion of the kidneys and an acute form of appendicitis. On ultrasound, it is ideal to view the topography of the peritoneal organs.

In general, as experts note, the procedure is completely harmless and safe, it is permissible to carry it out quite often, due to the absence of the influence of ultrasonic waves on the structural structure of cells.

To judge how correctly the peritoneal organs are located, to determine the degree of development of pathological conditions, specialists can perform not only ultrasound, but also CT or MRI. The presented diagnostic techniques easily identify focal lesions, as well as fatty liver regeneration, dystrophic and ischemic algorithms, which can become more intense with age.

At the same time, for example, stones (deposits of calcium salts) cannot be fixed on MRI images and pictures. In the vast majority of cases, their cost is approximately comparable to the implementation of a diagnostic examination through ultrasound.

Considering all this, it is safe to say that today specialists know everything about the structure of not only internal organs, but also all those structures that enter the abdominal cavity. It is they who provide 100% coordinated work of the body, fully providing all physiological processes.

1. Can cancer be prevented?
The occurrence of a disease such as cancer depends on many factors. No one can be completely safe. But everyone can significantly reduce the chances of a malignant tumor.

2. How does smoking affect the development of cancer?
Absolutely, categorically ban yourself from smoking. This truth is already tired of everyone. But quitting smoking reduces the risk of developing all types of cancer. Smoking is associated with 30% of cancer deaths. In Russia, lung tumors kill more people than tumors of all other organs.
Eliminating tobacco from your life is the best prevention. Even if you smoke not a pack a day, but only half, the risk of lung cancer is already reduced by 27%, as the American Medical Association found.

3. Does excess weight affect the development of cancer?
Keep your eyes on the scales! Extra pounds will affect not only the waist. The American Institute for Cancer Research has found that obesity contributes to the development of tumors in the esophagus, kidneys, and gallbladder. The fact is that adipose tissue serves not only to store energy reserves, it also has a secretory function: fat produces proteins that affect the development of a chronic inflammatory process in the body. And oncological diseases just appear against the background of inflammation. In Russia, 26% of all cancer cases are associated with obesity.

4. Does exercise help reduce the risk of cancer?
Set aside at least half an hour a week for exercise. Sport is on the same level as proper nutrition when it comes to cancer prevention. In the US, a third of all deaths are attributed to the fact that patients did not follow any diet and did not pay attention to physical education. The American Cancer Society recommends exercising 150 minutes a week at a moderate pace or half as much but more vigorously. However, a study published in the journal Nutrition and Cancer in 2010 proves that even 30 minutes is enough to reduce the risk of breast cancer (which affects one in eight women in the world) by 35%.

5.How does alcohol affect cancer cells?
Less alcohol! Alcohol is blamed for causing tumors in the mouth, larynx, liver, rectum, and mammary glands. Ethyl alcohol breaks down in the body to acetaldehyde, which then, under the action of enzymes, turns into acetic acid. Acetaldehyde is the strongest carcinogen. Alcohol is especially harmful to women, as it stimulates the production of estrogen - hormones that affect the growth of breast tissue. Excess estrogen leads to the formation of breast tumors, which means that every extra sip of alcohol increases the risk of getting sick.

6. Which cabbage helps fight cancer?
Love broccoli. Vegetables are not only part of a healthy diet, they also help fight cancer. This is also why recommendations for healthy eating contain the rule: half of the daily diet should be vegetables and fruits. Especially useful are cruciferous vegetables, which contain glucosinolates - substances that, when processed, acquire anti-cancer properties. These vegetables include cabbage: ordinary white cabbage, Brussels sprouts and broccoli.

7. Which organ cancer is affected by red meat?
The more vegetables you eat, the less red meat you put on your plate. Studies have confirmed that people who eat more than 500 grams of red meat per week have a higher risk of developing colon cancer.

8. Which of the proposed remedies protect against skin cancer?
Stock up on sunscreen! Women aged 18-36 are particularly susceptible to melanoma, the deadliest form of skin cancer. In Russia, in just 10 years, the incidence of melanoma has increased by 26%, world statistics show an even greater increase. Both artificial tanning equipment and the sun's rays are blamed for this. The danger can be minimized with a simple tube of sunscreen. A study published in the Journal of Clinical Oncology in 2010 confirmed that people who regularly apply a special cream get melanoma half as often as those who neglect such cosmetics.
The cream should be chosen with a protection factor SPF 15, apply it even in winter and even in cloudy weather (the procedure should turn into the same habit as brushing your teeth), and also do not expose yourself to the sun's rays from 10 to 16 hours.

9. Do you think stress affects the development of cancer?
By itself, stress does not cause cancer, but it weakens the entire body and creates conditions for the development of this disease. Research has shown that constant worry alters the activity of the immune cells responsible for turning on the fight-and-flight mechanism. As a result, a large amount of cortisol, monocytes and neutrophils, which are responsible for inflammatory processes, constantly circulate in the blood. And as already mentioned, chronic inflammatory processes can lead to the formation of cancer cells.

The human body is similar to a complex mechanism in which all parts are interconnected and work smoothly. Published by us in this article to understand how the internal organs of a person are arranged, the layout in the photo with inscriptions will help to understand the structure of the anatomy of a man and a woman.

Each organ has its own localization, structural features, main and auxiliary functions. That is why, very often, when one organic element fails, several others indirectly suffer. In order to better feel your body and help it cope with emerging difficulties in the form of diseases or injuries in a timely manner, a person needs to know the precise location of his internal organs in detail.

The body of a man and a woman includes three main zones to complete a certain group of organs. These are the thoracic and abdominal sections, as well as the region of the small and large pelvis. Single internal organs that do not have grouping are located in the intervals between the main zones.

General familiarization with the location of organs inside the human body begins with thyroid gland which settled below the larynx in the lower front of the neck. This important element of the body during life can slightly move deeper or lower, which is normal. Another resident of the human body that is expressed and does not have a group formation is diaphragm, is located between the zones of the thoracic and abdominal regions. The main function of this organ is responsible for the free expansion of the lung area for the unhindered passage of air.

Thoracic region of the body and its components

The permanent and important organs of the sternum are the heart, lungs, bronchi and thymus gland.

• The main muscle of the human body heart, an internal organ located above the diaphragmatic zone, between both lungs, with a significant shift to the left side. The main task that ensures the vital activity of the human body as a whole lies in pumping the circulatory system. The heart muscle is very often individualized in its shape, which is due to several reasons. The visual appearance of the heart can be affected by gender, age, lifestyle, and overall health.
• The pulmonary system consists of a symmetrical arrangement lungs, filling most of the plane of the chest region from the collarbone to the diaphragm. In the photo of the layout inside, the external appearance of the elements responsible for the breathing apparatus has a cone-shaped elongated appearance, reliably protected by ribs.
• Bronchi formed in the form of a regularly branched plant, the base - the stem of which emerges from the trachea and germinates in both lungs. Despite the same functionality, the visualization of the bronchial branches is not symmetrical. The right organ is somewhat thickened, in contrast to the left, and noticeably shortened. Within their system, the bronchi are divided into subspecies: lobar extrapulmonary, segmental extrapulmonary, subsegmental intrapulmonary and bronchioles, smoothly flowing into the alveoli.
• thymus- the thymus gland, the main immunologist of the human body, is an internal organ located in the upper back of the sternum and having a fork-shaped shape.

Abdominal organs

This cavity is occupied by such elements as the stomach, liver, pancreas, gallbladder, kidneys, adrenal glands, spleen and intestinal tract.

• Food bag - stomach has elastic muscle tissue that allows the organ to stretch as it fills. In the human diagram, the location of the main food receptacle is located immediately below the diaphragm, shifting slightly to the left. Although pain in the event of a malfunction of the stomach is more often localized in the center. The main function of this organ is to break down food with the help of gastric juice into useful and nutritious substances.
• Liver, as a filtering mechanism, is a multifunctional and essential element of the digestion process. It is located in the right hypochondrium and has an uneven two-lobal structure, with a clear dimensional advantage on the right. The task of hepatic activity is to ensure the protection of the body from intoxication, the production of cholesterol and the regulation of intercellular metabolism.
• Pancreas with its ability to produce enzymatic substances for the digestion of food, is located according to the scheme of the internal organs of a person in the upper left part of the peritoneum, behind the stomach. It is actively involved in metabolic processes and supplying the body with natural insulin.
• gallbladder- a small, but quite significant organ for the functioning of the gastrointestinal system. It produces the bile necessary for the body in the right middle sector of the abdominal cavity. Despite its size and ovoid shape, it plays a huge role in digestion, malfunctioning of which causes not only discomfort in the form of nausea, vomiting and pain on the right, but also participates in the development of gastric and duodenal ulcers.

Human internal organs: pictures of the abdominal cavity

• Twins in the abdomen are kidneys, which play an important role in the urine - the excretory system. They have a bilateral location in the back and bottom of the peritoneum, with some asymmetry of fit due to a slight difference in size. The left kidney is slightly larger than the right kidney and is slightly higher. Their appearance visually resemble curved bean fruits.
• adrenal glands, as satellites of the previous paired organs, are also located on both sides of the human abdominal cavity and carry significant functionality of the hormonal and endocrine systems. They produce and release more than 25 hormones into the blood, including androgens, corticosteroids, and adrenaline. They receive impulses from the nervous system due to the components of the medulla and cortex that fill these organs, which helps to correct the processes of excitation and inhibition during stress and disorders.
• The basis of the scheme of hematopoiesis and the immune system - spleen, found its location in the upper left region of the abdominal plane in the form of an elongated oval. It protects the human body from various kinds of infections, enhances metabolism, regenerates platelets and red blood cells, and very rarely gives pain signals about malfunctions in its work.

Internal organs of the small and large pelvis

The urinary-genital system of the body consists of the bladder and the reproductive system, which in the female body contains the uterus and ovaries, and in the male - the seminal vesicles and the prostate gland.

• Bladder located in the lower pelvis behind the pubic bone. The main function of this organ is of a collective nature with periodic disposal of accumulated urine through the urethra. It has elastic muscle tissue that stretches with the presence of contents and contracts after emptying. In an empty state, the bladder is localized clearly behind the pubis, and when filled with urine, it begins to grow upward, significantly changing its shape to an ovoid. An increase in the organ has individual boundaries, sometimes reaching right up to the umbilical point. When the urinary activity of the bladder fails, the impulses of this may be soreness during urination and cramping pains in the lower abdomen.
• Uterus located directly above the bladder in the middle of the pelvis. The most elastic organ of the female body in a calm state has a length of about 7 cm, stretching to a significant size during pregnancy. The sufficiency of free near the uterine space inside the body allows the uterus to be also the most mobile organ, capable of shifting due to the fullness of the bladder and intestines. The shape in the form of a flattened pear is rounded at the bottom, in the area of ​​transition to the cervix. The main task of the body is the continuation of the human race. The reservoir for the formation and bearing of the baby is equipped with a three-layer structure of the walls responsible for the supply of nutrients, and also has protective functions and sufficient muscle tone necessary for the birth process.
• ovaries- a paired organ of an exclusively female body, responsible for the ability to bear children. In addition to the main task, which is the formation and maturation of germ cells, it is involved in the production of sex and steroid hormones. They are located on the diagram of the internal organs on both sides of the uterus, located symmetrically in relation to it. The cyclic activity of the ovaries is shown by the menstrual process, which characterizes the monthly renewal of the cellular complex developed for fertilization.
• seminal vesicles- organs - twins of an exclusively male body, located in the posterior lateral region relative to the bladder. They have an excretory function, producing the necessary secret for nourishment and promotion of spermatozoa. They take an active part in the process of ejaculation.
• Prostate is located in the layout of human organs in front in the central lower region of the small pelvis of a man, located under the bladder. In appearance, it resembles a chestnut in shape, with a furrow division in the center. The main task of the prostate is to secrete the secretory fluid that is basic in the composition of the sperm, rich in immunoglobulins and enzymatic substances. An auxiliary function is to block the exit of the urethra in a state of erection. Also, the prostate gland is involved in the process of ejaculation, due to its ability to intense contraction of muscle tissue, and contributes to the liquefaction of the consistency of sperm in general to enhance the mobility and vitality of spermatozoa.

The human body is an object of constant research and experimentation. The preservation and protection of internal organs is an innate instinct of any living being. Unfortunately, people do not always treat their body with due respect. And these are not necessarily bad habits or an unhealthy lifestyle. Heavy physical labor, hypothermia or other unforeseen situations can cause a malfunction of internal systems, so a clear knowledge of the location of one's vital organs will help a person determine the cause of discomfort and facilitate an accurate diagnosis for the attending physician.

The organs of our body have their own structure and location. Knowing the location of a particular organ will help you independently understand what exactly hurts you. And then go to the appropriate doctor for a solution to health problems. All systems in our body are highly interconnected. To understand what and where is, our diagrams will help you. With them, the location of the internal organs of a person will remain in your memory for a long time.

The human body is usually divided into three cavities - thoracic, abdominal and pelvic. The diaphragm separates the thoracic cavity from the abdominal cavity. This is a special muscle that expands the lungs. Usually, the study of internal organs begins from top to bottom. And the first organ on this path is the thyroid gland. It is located in the neck area under the Adam's apple. But the place of its localization cannot be called permanent, because it can change its size. There are also cases of its omission.

chest cavity

The organs of the chest cavity include the heart, lungs, bronchi and thymus gland. Each of them has its own location and functions. The listed organs are shown below.

Heart

The heart is the main element of the cardiovascular system. Its activity ensures the movement of blood in the vessels. The place of this organ is behind the ribs above the diaphragm. The heart is located between the lungs, but its position relative to the midline of the body is asymmetrical. Two thirds of the organ is on the left side, and one third on the right. It is noteworthy that the shape of the heart in people is not the same. It is influenced by gender, age, physique, lifestyle, health status, etc.

Lungs

Studying the location of the internal systems and organs of a person, we move on to the lungs. Their main task is the regulation of the respiratory system. They practically fill the entire chest cavity, located closer to the back. The lungs can change their size, depending on the phases of our breathing. Their shape resembles a truncated cone. The upper part of the lungs is directed to the supraclavicular fossa. And their lower part rests against the domed diaphragm.

Bronchi

The bronchi are very similar to tree branches. They are located inside the lungs. There, the organ branches and forms the bronchial tree. The left bronchus differs from the right one in that it is longer, thinner, and also less vertically located. This body is also divided into orders:

• 1 order - lobar extrapulmonary bronchi;
• 2 order - segmental extrapulmonary bronchi;
• 3-5 order - segmental and subsegmental intrapulmonary bronchi;
• 6-15 order - small intrapulmonary bronchi.

Thymus

The thymus gland is located in the upper part of the chest. It got its name from its appearance, which resembles a two-pronged fork. For a long time, the organ remained mysterious and poorly understood. But now doctors have found out that this gland is responsible for the body's immune system.

Abdomen

The following organs are located in the abdominal cavity:

• Stomach,
• Pancreas,
• Liver,
• gallbladder,
• Spleen,
• Intestines,
• kidneys,
• Adrenals.

Stomach

The location of the stomach is on the left under the diaphragm. The organ is bag-shaped. Its structure easily allows you to change the size, because the fullness of the body is constantly changing. The stomach stores food and performs its initial digestion. Gastric juice helps him cope with the task.

Pancreas

Next is the pancreas. It is located behind the lower part of the stomach. Its function is to ensure the exchange of fats, proteins and carbohydrates. This is a very large gland with the functions of internal and external secretion.

Liver

The liver is located at the top right, directly below the diaphragm. It is a super important body cleansing organ. Consists of two parts - left and right. The right one is much larger than the left one. The liver neutralizes foreign substances that enter the body through the digestive system. Provides glucose supply, regulates lipid metabolism and performs many more useful functions.

gallbladder

The gallbladder is located at the bottom of the liver. More precisely in its right longitudinal furrow. The gallbladder is shaped like a sac, the size of which is comparable to a chicken egg. The organ is filled with bile, which comes directly from the liver and is involved in the overall digestive process. In the bladder, bile is concentrated and then moves into the duodenum.

Spleen

Behind the stomach, in the upper left part of the abdominal cavity is the spleen. In shape, it looks like an elongated hemisphere. The organ is responsible for the immune system, and also performs the functions of hematopoiesis. The spleen also disposes of defective blood cells.

Intestines

The intestines are located in the lower part of the abdominal cavity under the stomach. It is a long folded tube. It begins with the small intestine, which then passes into the large intestine. The large intestine, in turn, ends with an anus. 70% of immune cells are located in the intestines, so the general health of a person depends on its good functioning.

kidneys

The kidneys are a paired internal human organ. Their shape resembles beans. These organs are involved in the genitourinary system. Their localization is the lumbar region, on the sides, behind the parietal sheet of the peritoneum. As a rule, the size of the right kidney is smaller than the size of the left. The main function of the kidneys is the formation and excretion of urine.

adrenal glands

The organ got its name from its location. The adrenal glands are located directly on top of the kidneys. They are paired glands of the endocrine system. Their functions include the regulation of metabolism, adaptation to stressful situations, etc.

Organs of the large and small pelvis

In women and men, the structure of the small pelvis is different. There is one large common organ - the bladder. It is located in the lower part of the small pelvis. It is a hollow organ that stores urine. The bladder plays one of the leading roles in the urinary system.

Pelvic organs in women

The female pelvic organs include:

• Vagina. During childbirth, it performs the function of the birth canal. Inside the vagina has many folds, it is covered with a mucous membrane. This structure allows the body to stretch greatly, which simplifies the birth of a child.
• Ovaries. The ovaries are a paired organ, located on the sides at the very bottom of the woman's abdomen. The shape resembles sacs, inside they contain eggs. It is in the ovaries that the female sex hormones - progesterone and estrogen - are produced.
• Uterus. It is located in the very center of the small pelvis, resembles a pear in shape. Its purpose is to bear a fetus. The walls of the uterus are made up of many muscles that grow with the fetus. During childbirth, they begin to contract sharply, pushing the baby into the birth canal.
• The fallopian tubes. One end is connected to the uterus, the other - to the ovaries. The eggs travel through the tubes to the uterus.
• Cervix. It is the lower part of the uterus, which attaches its cavity to the vagina. During pregnancy, the cervix reliably closes the entrance to the uterus, at the time of childbirth it opens.

Pelvic organs in men

The male pelvic organs include:

• Prostate. Located under the bladder. Both ejaculatory streams pass through this gland, and the urethra also begins. The function of the prostate gland is to secrete a special secret into the semen.
• seminal vesicles. They are a paired organ. They are located behind and to the side of the bladder, as well as on top of the prostate. The seminal vesicles produce fructose, which is very important for maintaining the proper quality of spermatozoa.
• Testicles. They are located inside the scrotum. Produce testosterone (male sex hormone), as well as sperm.

Conclusion

Knowing the location of our internal organs, it is much easier for us to understand what is the source of pain. When examining a doctor, we can give more accurate information about our pain sensations. And this, in turn, will accelerate the formulation of an accurate diagnosis. If a problem is identified early, it can be resolved more easily and quickly.

The structure of the human body has been formed over millions of years of natural evolution. Nature has created an innumerable number of variants of creatures in order for Homo sapiens to appear. So what did she get?

In contact with

Cellular and extracellular structures

The internal organs of a person consist of two types of "building material". The first is cells, the basis of tissues, which carries genetic information and is the “bricks” from which the “house” is built. The second is the connective fluid, a kind of “cement” that is located between the cells and performs various functions depending on the location.

The cell and its structure

Activity fully provided by three biological constructs, despite the fact that there are about two hundred types of such a structure in the human body:

1. Surface apparatus is the outer layer of the cell, which helps it recognize the surrounding substances and let them in or out.
2. Membrane complex, due to which all metabolic reactions occur, that is, the cell “digests” the consumed trace elements and produces a finished product that either absorbs itself or infuriates itself. Also here are special temporary inclusions, for example, melanin or hemoglobin.
3. Nucleus, which includes -structures, which allow, when dividing, to form exactly the same organic structure, and therefore, in the end, a human being does.

Attention! Cells are the base that makes up all the major parts of the human body, but they don't always work alone. Thanks to special processes, they form syncytium - a structure of many identical elements. There are also elements containing several , - symplasts.

extracellular fluid

Liquid, located between cells, consists of water and biopolymers, such as collagen or elastin. Its main functions are to provide efficient and stable work of cellular structures and feed them, dissolving in themselves the beneficial substances "supplied" by the blood. In a standard human being, there are about 11 liters of such liquid.

Tissues of the human body

There are four types of tissue in the human body. Each of them performs its own unique function or a number of them, which ensures a full life:

1. epithelial tissue is the outer surface of organs, and it is also the skin, cornea of ​​​​the eyes, serous membranes. In addition, many glands are composed of tissues of epithelial origin.
2. nervous tissue- specific cells that are designed to "communicate" all the elements inside and interact with the body with the outside world. Such a "material" provides the conduction of impulses that give signals to the brain so that it can react and perform an adequate action. For example, withdraw your hand if it's hot.
3. connective tissue in the body most of all, because it is not responsible for any specific function, but plays a supporting role in all human organs. It exists in four states - solid, being the basis of bones; fibrous, forming ligaments; liquid - this is blood, lymph and other liquid media; gel-like - the basis for the formation of cartilage.
4. Muscle designed to form the motor apparatus. Contracting, it helps him move in space or ensure the functioning of internal organs.

The layout of organs and their systems is considered both from the outside and in a full-length section, which allows you to better understand their structure.

External details

In addition to the listed structural elements, it is customary to pay attention to the outer structure of man. It's simple and visible to the naked eye:

• head;
• frame;
• breast;
• upper paired limbs, that is, hands;
• lower paired limbs - legs.

Internal organs and their systems

The insides of a person imply a division into systems, and the layout of each requires special attention:

1. implies interconnected bone tissue, which is the solid foundation of the whole body, the base for everything else.
2. Connection system- the support of the body, creating places for all structural elements.
3. Muscular "construction"- muscles that take up space on the bones and other viscera and make them move.
4. digestive apparatus, which includes everything related to the assimilation of food, from the mouth to the large intestine.
5. Respiratory systems a provides saturation of the body with oxygen and, starting from the nasopharynx, includes, among other things, the circulatory function, which ensures the saturation of tissues and the removal of carbon dioxide from them.
6. urinary mechanism cleanses of water-soluble metabolic residues and is located in the abdominal region and below.
7. Sexual spheres but is needed for procreation and is located in the pelvic area.
8. Heart and blood vessels"Feed" the whole body with useful substances and remove metabolic products. Spreads throughout the body to reach every part of it.
9. network of nerves provides contact with the external environment and internal interaction. It is located in a dense network throughout the body.
10. The structure of human organs includes endocrine glands needed for the release of hormones. Glands are everywhere.
11. Lymphoid formations- generation of immunity. They are needed to protect against foreign substances and are located throughout the body.
12. sense organs These are eyes, ears, nose and so on.
13. The general cover is the skin, hair, nails, sweat glands - everything that comes into contact with the external environment.

Important! When studying the structure of the body, it is worth knowing that some systems are combined into apparatuses, as they have similar or intermittent functions, for example, the musculoskeletal system, including muscles, bones and the connective system.

What is in…

Understanding the human structure, you need to find a drawing describing certain zones. Usually pay attention to three places - chest, abdomen and large and small pelvis. The latter is important for distinguishing a man from a woman. It is also worth knowing the structure of the brain, as it is responsible for the functioning of everything in the human body.

Abdomen

A person is divided by specialists into three "floors": upper, middle and lower. In each, you can feel certain components:

1. Top floor includes the hepatic and omental bags, as well as the pancreatic fissure. The first includes part of the stomach and spleen, as well as the right hepatic lobe. The second contains the lymph nodes that regulate the outflow of lymph.
2. middle floor located under the colon and omentum. This is the intestine itself, which contains various intestines, as well as a mesentery filled with fiber with blood, lymphatic vessels and nerves.
3. lower floor includes the urinary and genital apparatus - about them below.

The layout of each floor intersects with the neighboring ones and often captures the same elements, which is due to their close interaction.

Breast

In the human thoracic cavity is located:

• trachea which brings air into the lungs;
• bronchi- open access to the received oxygen in the lungs;
• lungs, which directly oxygenate the blood. If you look at the picture, they take up the largest amount of space in this cavity;
• esophagus located between the two halves of the lungs;
• thymus- counteracts incoming infections;
• heart- pumping blood and being the basis of oxygen delivery;
• diaphragm- This is a dividing line of human organs in the body, which delimits the pulmonary and abdominal cavity.

Having figured out how the human body works in the torso, we can confidently assume that the location of most of its parts is already known. It remains to understand how the brain works and what is the difference between a man and a woman.

Head

To understand how the human body works, it is worth understanding the “content” of your own brain. It includes four key areas:

1. two hemispheres, providing complete control over mental and physical processes.
2. Cerebellum controls balance, allowing a person to stand straight and adequately perceive himself in space.
3. Pons needed to transfer data from the body to the brain and vice versa.
4. Another bridge is located below everything and connects with the dorsal. He perceives information and transmits it "above".

The location of human organs in the body depends on gender identity. Let's see what the difference is here.

Man and woman

Human anatomy, the internal organs of a woman differ from the opposite sex by the presence mammary glands, uterus and the specific structure of the urinary system. In men, in turn, in the pelvic area are located testicles, prostate gland and vas deferens and the process of urine output is also arranged in its own way.

Attention! The weight and size of the internal organs in men is greater than in women, in the vast majority of cases. The reverse situation can only be if a very large woman will "oppose" a short and thin man.

Conclusion

The location of human organs in the body of both sexes is extremely similar, they differ only in size and gender. Otherwise, all systems are placed in the same way and functionally do not differ from each other.
