Pylorus

Pylosor is a gland-type organ in the human body, located on the walls of the stomach. The function of the pylorus is the passage and evacuation of chyme between the upper part of the stomach and the duodenum. Normally, this duct opens after eating and closes 45 minutes after it enters the body due to the absence of an irritant - hydrochloric acid, which is released in the upper parts of the stomach. When food enters the intestines from the stomach, the pylorus is in a closed state. The state of the pylorus of a healthy person can change during stressful situations and hormonal disorders, and this happens passively and does not require the participation of the pylorus itself.

Pylorus is a special muscle in the abdomen located next to the duodenum. It plays an important role in digestion and serves to control the process of moving food from the stomach to the intestines. The pyloris controls the entry and exit of food from the digestive tract and is one of the most important muscles in the human body.

Pylorus is a fold of mucous membrane covered with muscle tissue and subcutaneous tissue. The muscles are in the longitudinal direction and have a narrowed shape at the point where it passes into the stomach. Anatomically, the pylorus is located between the pylorus and the antrum of the stomach.

The normal functioning of the pylorus ensures adequate blood circulation in the mucous membrane of the esophagus and stomach, which, in turn, helps maintain its integrity and permeability. Releases of adrenaline and other neurotransmitters often stimulate pyloric spasm, but over a longer period of time this can lead to irreversible changes in pyloric function and the occurrence of gastric reflux. Functions of the pylorus:

It regulates the flow of gastric juice into the upper intestines by creating an obstacle to the release of stomach contents - this occurs while simultaneously contracting the pylorus of the stomach; It regulates the acidity of the stomach contents when food arrives; The pyloro is the area of ​​the body where the border between the stomach and intestines lies. This area is home to several important processes that affect digestion and overall health.

Structure

This is an oval muscle formation that looks like a cylinder. The diameter of the pylori is about 7 cm. Smooth muscles are connected to both sides of the pylori; they additionally control the contractile function of the pylori. Deep in each muscle there are intertwining tubular structures, each of which is a blood vessel. Between the two muscles there are glands with different functions: some secrete
