Most of us know where the stomach is in a person, as this is one of the main organs.
General information
The stomach is called the digestive organ, which performs mechanical and enzymatic processing of food that has fallen into its cavity. This is the enlarged part in the digestive canal. The walls of the organ in its composition have a large number of glands, the task of which is the secretion of gastric juice.
The location of the stomach in a person is very simple: it is located in the upper part of the abdominal cavity under the dome of the diaphragm and is slightly shifted to the left. The size of this body is quite problematic to determine - it depends on age, length, and also on the person’s gender. If we talk about the average figure, then this is about half a liter.
What exactly happens in the stomach?
Where a person’s stomach is located is already a little clear, but now you need to figure out what exactly is happening in its inner part. So, immediately after getting a certain amount of food, quite interesting processes begin to start.
To begin with, a large amount of various acids begins to act on food that has entered the stomach, since their task is to decompose all compounds, even the most complex ones.
Any chemical compound from the absorbed food reacts with acids that are in the stomach. But in each individual case, a wide variety of reactions can occur, as a result of which the final products are obtained. They are what the human body needs.
Then the reaction products that have already formed inside the stomach act on its receptors, transmitting to the brain information that the food lump contains some substances. In order to determine the substances that are in food, this organ does not break down the entire portion - a few percent is enough.
Purpose of the organ
If you do not delve into many nuances, then we can say that the stomach is designed to very quickly determine the substances found in food, and then immediately inform the brain about it.
Then the latter immediately makes a decision regarding which enzymes must be developed in order to digest food. Simply put, the stomach can be called the main laboratory, which conducts very important studies in the shortest possible time, but at the same time performs everything efficiently and efficiently.
Main functions
Where is a person's stomach located? Before answering this question, you must first understand what functions in the body are assigned to it:
1. Grinding and partial digestion of food that enters its cavity.
2. The production of gastric juice.
3. Wetting and mixing the food lump.
4. Transportation of food products further along the digestive tract.
5. Here there is a partial absorption into the blood of decay products that arose as a result of the reaction of stomach acid with substances contained in food.
6. In the stomach, under the influence of hydrochloric acid, all microbes are destroyed, thus the products are disinfected.
Human Stomach. Anatomy
This organ consists of the cardiac section, subcardia, bottom, antrum, body.
The cardinal section is one of the parts of the stomach, it is directly adjacent to the cardia.
If we consider the small curvature, then this distance is approximately 2-3 centimeters.
Subcardia is located slightly lower than the cardiac section (along the lesser curvature by 5 centimeters).
The bottom is represented by the part of the stomach that is slightly higher than the esophageal-gastric junction.
The antrum has a proximal restriction by a line from the corner of the stomach, located in the very middle, exactly where the large curvature passes.
The body of the stomach is called that part of it, which is located from the subcardia to the antrum itself.
Also, the body under consideration includes two curvatures, two surfaces, and two holes.
Small curvature is located on the right edge of the stomach. Two sheets of the gastrohepatic ligament are attached directly to it.
Large curvature has a size that exceeds the small by 3-5 times. Its highest point coincides with the cartilage of the left sixth rib.
The surfaces include the lower-back, as well as the front-upper.
The stomach has two holes. The first is called cardiac, through it the cavity of the stomach communicates with the esophagus, and the second - pyloric, it connects the stomach with the duodenum.
Major diseases
Today, the most common ailments are gastritis, ulcers and cancer. The latter is already a consequence of diseases that the human stomach can acquire. Photos of the affected organs illustrate pathological changes. The main reason for the development of ailments is the poor environmental situation, as well as food, in which almost nothing is left natural.
The aggravation of a person’s state of health is primarily his fault, because he does not go to the hospital when nothing hurts him. But when pain occurs, it can be very late.
The same situation with one of the main organs: while it does not bother, many people do not even know where the person’s stomach is. It is best to undergo preventive checks that can not only determine the onset of serious diseases in time, but also save a person’s life.
It is necessary to consider the disease in more detail:
- Gastritis is a disease that is characterized by inflammation of the mucous membrane of the wall of the stomach.
Gastritis is of two types: with increased or with reduced acidity of the gastric juice produced by the glands.
- An ulcer occurs as a result of the aggressive effect of gastric juice on the gastric mucosa. As a result, recesses (ulcers) appear in its structure, the dimensions of which reach one centimeter.
If you conduct examinations and treatment on time, then you can overcome these ailments with the help of drugs and diets. It is very useful to know where the person’s stomach is and how to deal with his main ailments in order to avoid serious consequences.
