Most of us know where the human stomach is, as it is one of the main organs.
General information
The stomach is a digestive organ that performs mechanical and enzymatic processing of food that has entered its cavity. This is an enlarged part in the alimentary canal. The walls of the organ in their composition have a large number of glands, whose task is to secrete gastric juice.
The location of the human stomach 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 side. It is rather problematic to determine the size of this organ - it depends on the age, extension, and also on the gender of the person. 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 is already a little clear, but now we need to figure out what exactly happens in its inner part. So, immediately after a certain amount of food has been ingested, quite interesting processes begin to run.
To begin with, a large number of different acids begin to act on the food that has entered the stomach, since their task isdecomposition of all compounds, even the most complex ones.
Any chemical compound from the ingested food reacts with the 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 products of the reaction that have already formed inside the stomach act on its receptors, transmitting to the brain information that the food bolus contains certain substances. In order to determine the substances that are in food, this body does not break down the entire portion - a few percent of it 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 in food, and then immediately report this to the brain.
The latter then immediately decides which enzymes should be produced in order to digest the food. Simply put, the stomach can be called the main laboratory, which conducts very important research in the shortest possible time, but at the same time does everything efficiently and efficiently.
Main Functions
Where is the human stomach? 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. Gastric productionjuice.
3. Wetting and mixing the food bolus.
4. Transporting food further down the digestive tract.
5. Here, partial absorption into the blood of decay products occurs, which arose as a result of the reaction of gastric acid with substances contained in food.
6. In the stomach, under the action of hydrochloric acid, all microbes are destroyed, thus disinfecting the products.
Human stomach. Anatomy
This organ consists of cardia, subcardia, fundus, 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 below the cardiac region (along the lesser curvature by 5 centimeters).
The fundus is represented by the part of the stomach that is slightly higher than the esophagogastric junction.
The antrum has a proximal delimitation by a line from the corner of the stomach, located in the very middle, exactly where the greater 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 structure of the considered body includes two curvatures, two surfaces and two holes.
The lesser curvature is located on the right edge of the stomach. Two sheets of the gastrohepatic ligament are attached directly to it.
Greater curvature has a size that exceedssmall 3-5 times. Its highest point coincides with the cartilage of the left sixth rib.
Surfaces include bottom-back and front-top.
The stomach has two openings. The first is called cardiac, through it the stomach cavity communicates with the esophagus, and the second is called pyloric, it connects the stomach with the duodenum.
Major diseases
To date, the most common ailments are gastritis, ulcers and cancer. The latter is already a consequence of diseases that a person’s stomach can acquire. Photos of the affected organs illustrate pathological changes. The main reason for the development of ailments is poor environmental conditions, as well as food in which almost nothing natural is left.
The deterioration of a person's he alth is primarily his fault, because he does not go to the hospital when he has no pain. 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 a person's stomach is. It is best to undergo preventive checks, which can not only detect the onset of serious diseases in time, but also save a person's life.
It is necessary to consider diseases in more detail:
- Gastritis is a disease characterized by inflammation of the lining of the stomach wall.
Gastritis is of two types: withincreased or decreased acidity of the gastric juice produced by the glands.
- An ulcer occurs as a result of the aggressive action of gastric juice on the gastric mucosa. As a result, depressions (ulcers) appear in its structure, the size of which reaches one centimeter.
If you carry out examinations and treatment in time, then you can overcome these ailments with the help of drugs and diets. It is very useful to know where a person's stomach is and how to deal with its main ailments in order to avoid serious consequences.
