How are the internal organs of a person: photo and video anatomy of human organs with the names, functions and structure of internal organs

on 03.12.2017

Each organ of the human body performs its own - the most important, unique function, and all of them together constitute one complex, coherently working mechanism. All the details of this mechanism are inextricably linked, and if one “spare” is damaged, it will have consequences for the whole body. Therefore, it is important to knowwhere and how is every organ of the human body, and if necessary, determine what exactly is bothering you and which physician should consult for consultation. This article ishuman body guidein which you will visually see how the most important organs of the male and female bodies are located, and learn about their main functions and features.

Cavities of the human body in which organs are located

anatomiya-cheloveka-englishIn the human body, there are three cavities in which both the main organs of the person are “manned”, and these are:

  • Thoracic
  • Abdominal
  • Pelvic.

In addition, a muscle is placed between the chest and abdominal cavities, which allows the lungs to expand during breathing - the diaphragm. Above, on the front of the neck, there is a thyroid gland, the location of which may be higher or lower in people with different health conditions and different ages. In men, over the thyroid gland is the Adam.
In this article we will also separately consider the structure of the human brain.

How are the internal organs of a person?

Let us examine in more detail which organs “fill” all the cavities of the human body, how they look, where they are and what they function for.

Organs located in the human thoracic cavity

If we talk about the shape of the human heart, there will be no single answer. Both the size and shape of the heart is determined by age, the presence of chronic diseases, sex, physical development and other factors.

The main role among the organs of the respiratory system rightfully endowedlungs, and almost 2/3 of the chest space is occupied by them. The size of the lungs varies with the depth and phase of breathing. If we talk about the shape of the lungs, they resemble a truncated cone, the top of which tends to the area above the collarbone, leaning on a convex diaphragm.

Thymus- a body about which a couple of decades ago there is still little that could be told in anatomy lessons. Now it is proved that it plays perhaps the most important role in the immune system of any person.It received its name for its appearance, resembling a dessert fork.

How are the organs located in the human abdominal cavity?

Select the main organs that are located in the human abdominal cavity and dwell in more detail on the functions of each of them:

  1. Under the diaphragm, on the left, is placedstomach. This section of the digestive tract, which expands, representing a bag-shaped cavity. The more the stomach is filled, the larger its size, that is, its walls have the ability to stretch under the influence of the amount of food entering it. At rest, its length is 15-17 cm. Food is digested under the influence of the juice secreted by the stomach.

  2. Behind the stomach, slightly below it, housedpancreas- also an important component of the digestive system. This is a fairly large body that secretes pancreatic juice - a source of enzymes necessary for digestion. Without the pancreas, healthy metabolism of proteins, fats and carbohydrates in the human body would also be impossible.

  3. The most important organ of purification, the vital natural filter of the human body -liverwhich is located under the diaphragm, at the top of the abdominal cavity on the right side. The liver has a lobar structure, while the right side of the liver is much larger than its left lobe. Most of the toxins, harmful foreign substances, metabolic products are effectively eliminated from the body solely thanks to the liver, in addition, it carries out the synthesis of cholesterol in oragism.

  4. To accumulate bile, which comes from the liver and is involved in the digestive process, helpsgallbladderwhich is located in the lower "compartment" of the liver, along the right furrow. The shape of the bile resembles an oval-shaped sac, and its size does not exceed the volume of the chicken egg. It is filled with bile - a viscous substance of yellow-green color, which spills over the ducts into the duodenum.

  5. Hematopoietic and immune function hasspleen- slightly elongated, flat organ, located on the left, slightly behind the stomach. Not without the aid of the spleen, lymphocytes are formed, a filter of foreign substances and bacteria occurs, damaged platelets and red blood cells are “sorted out”.

  6. Just below the stomach is an organ, which is a long tube that is entangled in a circle. itintestineswhich in the right part of the body of man passes from its thin part into the thick part. Starting from the right and describing the so-called circle in a clockwise direction, the intestine descends to the left side of the abdominal cavity, and ends with the anus.
    Fact:70% of the cells of the immune system "live" in the human intestine, so your health directly depends on the smooth functioning of this organ.kak_pochistit_kishechnik
  7. Separately, it should be said about the appendix - a small process of the colon, located near the right wall of the peritoneum.AppendixIt is not a vital organ, but if it is inflamed, people speak of appendicitis, and then the appendix should be removed as soon as possible by surgery. Otherwise, acute peritonitis is possible, and even fatal.

  8. In the abdominal cavity "in the presence of" not only the digestive organs, but also the organs of the excretion system, such askidneys. The kidneys are located laterally in the lumbar region, behind the peritoneum. In size, each kidney does not exceed 5-6 cm in length and 3.5-4 cm in width, and in shape resembles a large bean.
    1461411163146869264The average mass of the kidney is small - from 100 to 200 g. It is worth noting that the function of the kidneys in the body is extremely important for life: they, like the liver, are natural filters of the whole body, regulators of chemical homeostasis.
  9. “To lead” the metabolism, to adapt the body to not always favorable external conditions and stresses, as well as to produce a number of hormones and androgens - the main functionsadrenal glands- organs of the endocrine system, which are located in the kidney area.

What is the largest organ in the human abdominal cavity?

If talkabout the largest organthe human body, then it isliver- The most powerful filter of the human body, "tool" against toxins and an active participant in all metabolic processes. If any process is disturbed in the liver, it will have negative consequences for the organism as a whole. The weight of the liver of an adult is approximately 1300-1500 kg.

If to mentionabout the longest bodyof our body, then this is definitely -intestineswhich fills the entire lower part of the peritoneum. The small intestine is a much narrower, more flexible and tangled tube than its thick "namesake." The total length of the intestine of an adult is about 4 m in life and more than 6 m after death.

How are the pelvic organs?

foto13Components of the genitourinary system, whose organs are located in the pelvic cavity of a person, are the following organs:

  1. Bladder- its location - the bottom of the pelvic zone, lower ureters. This organ has a collective purpose, that is, it is a reservoir for the accumulation of urine, which is periodically discharged through the urethra. The walls of the bladder are very elastic, and tend to contract after emptying. An empty urinary “lies” right behind the pubis and has a spherical shape, when filled, it begins to grow upwards, its shape is nearing ovoid.

  2. Uterus- its place is exactly above the bladder of the woman, horizontally, in the middle part of the pelvis. The uterus rightfully "won" the title of the most elastic internal organ of a woman. In an ordinary state, it has a length of no more than 6-7 cm and the shape of a flattened pear, whereas during pregnancy it can withstand the fetus, placenta and amniotic fluid. That is why around the uterus quite a lot of free space. Being a “vessel” for carrying a baby, the uterus has three layers of walls and sufficient muscle tone for the whole process of pregnancy and pushing the fetus.

  3. Ovaries- Another onefemale organ, "Participating" in childbirth, with their help, germ cells are formed and mature. They are located symmetrically on both sides of the uterus.
  4. Exclusivelymale paired organseminal vesiclesplaced behind the bladder, slightly laterally. Their function is to participate in the work of the excretory system, to develop a secret for the movement of spermatozoa and ejaculation itself.

  5. Prostate- located in the center of the bottom of the small pelvis of the man, in front, above the bladder. The shape is similar to chestnut, has a groove in the center. It produces a substance enriched in enzymes and immunoglobulins, and is the basis of the sperm. The prostate gland promotes the active contraction of muscle tissue and helps make the consistency of sperm more fluid in order to accelerate sperm.

What organs are located in the center of a person?

The internal organs are located in the center of the human body as follows: the larynx and the esophagus descend down from the pharynx. On the front wall of the neck groped thyroid. The esophagus goes along the center of the chest and is the ligament between the pharynx and the stomach.
In the center of the human abdominal region are:

Human organs on the left

On the left, the person has the following organs:

  • a heart- a little behind the lungs, but worth mentioningthat a small part of this organ lies in the right side of the chest;
  • stomach- immediately under the esophagus, at the top of the abdominal cavity and above the pancreas;
  • spleen- next to the stomach.

What organs are located on the right of a person?

On the right side of a person are such organs:

  • liver- in the subcostal area under the diaphragm;
  • gallbladder- immediately under the liver;
  • appendix.

Paired internal organs of a person

If you start your "anatomical look" from the very top, then you should consider pairedadenoidswho "live" in the upper part of the posterior pharyngeal wall, behind the nose, as well aspalatine tonsils- on the sides of the pharynx for the tongue. Also paired are4 parathyroid glands(are behind the thyroid).

Symmetrically with respect to the center of the chest cavity arebronchi(between the lungs) and themselveslungs(behind the ribs, which form a strong cocoon around them).

Paired abdominal organs:

  • kidneys and adrenal glands - in the lumbar area, while the left kidney is often 1 vertebra above the right;
  • ureters - kidney and bladder connectors.

Pelvic paired organs:

  • fallopian tubes and ovaries on the sides of the uterus in women;
  • gonads (testicles) in the scrotum in men.

The structure of the human brain

One can say of a human brain that it is a separate “state” with a complex structure and a multitude of functions assigned to each of its lobes and arteries. We offer to see an interesting visual video about how the human brain works.

How does the location of the internal organs of a woman during pregnancy?

During pregnancy, the “inner world” of a woman in all senses is experiencing an intensified “restructuring”, throwing all her strength at the carrying of the fetus and providing it with the most comfortable conditions while in her mother’s tummy. All life systems of the expectant mother undergo changes: cardiovascular, digestive, excretory, and other.

boli_v_mochevom_puzire_pri_beremennosti_979_928Under pressure from the growing uterus, the organs are “forced” to change their shape, and sometimes their position is even slightly corrected, which cannot but affect the state of health of the pregnant woman. These changes in the "inner" world often translate into:

So, the growing uterus shifts and moves apart the habitual arrangement of the internal organs of a pregnant woman:

  1. The liver and bile rise above the diaphragm, and the body's natural filter also takes a 90-degree turn.
  2. The stomach also lifts and contracts in volume, especially in the third trimester.
  3. The intestine "spreads" on the sides, because of which the tone of its walls is slightly reduced.
  4. The bladder is displaced to the very bottom of the pelvic area and its volume is significantly reduced, which increases and increases the urge of the pregnant woman “in a small way”.
  5. His heart is growing in size: he would, for he now has to pump blood for two.

Psychologists note that a woman who “perfectly well” knows the anatomy of her body is much easier to bear the discomfort associated with the displacement of her organs in the period of a child's bearing. Such women treat their bodies with greater gratitude and calmly tolerate his “whims”. After giving birth, all the internal organs of the woman fall into place, but the size of the uterus may remain a little more than the antenatal.
