Gatekeeper (Pylorus)

Gatekeeper (Pylorus): functions and structure

The pylorus (Pylorus) is the narrow right part of the stomach that connects to the duodenum. It performs an important function by regulating the release of food from the stomach into the intestines. The pylorus consists of a round muscle called the pyloric sphincter, which controls the opening and closing of the pyloric canal opening.

The pyloric sphincter is one of the most complex muscle structures in the human body. It consists of two inner circular muscle layers and one outer longitudinal layer. These muscle layers work together to control the passage of food through the pylorus.

When food reaches the pylorus, the pyloric sphincter closes to prevent the backflow of food from the intestine into the stomach. The sphincter muscles then begin to contract rhythmically, opening and closing the opening of the pyloric canal and allowing food to gradually leave the stomach and pass into the intestines.

Dysfunction of the pylorus can lead to various diseases of the gastrointestinal tract, such as gastritis, stomach ulcers, duodenitis and others. Some of these diseases may be associated with dysfunction of the pyloric sphincter, which leads to disruption of food digestion and nutrient absorption.

In conclusion, the pylorus (Pylorus) plays an important role in the process of digesting food and regulating its passage through the stomach into the intestines. The pyloric sphincter is a key structure in this process, controlling the opening and closing of the pyloric canal opening. Maintaining the health of the pylorus and its function is an important aspect of maintaining overall gastrointestinal health.

The pylorus is the narrowed right side of the stomach, which is located at the junction of the stomach and the duodenum. It is important for digestion, since it is here that the transition from the acidic environment of the stomach to the alkaline environment of the duodenum occurs.

The pylorus is supplied by a circular muscle called the pyloric sphincter. Contractions of this muscle cause the opening in the canal that connects the stomach to the duodenum to close, thereby preventing the contents of the duodenum from refluxing into the stomach.

In addition, the pylorus plays an important role in regulating the secretion of gastric juice. In particular, it controls the release of gastrin, which stimulates the secretion of gastric juice and pepsin, an enzyme that breaks down proteins.

However, in some diseases, such as peptic ulcers or gastroesophageal reflux disease, the pylorus can be compromised, leading to digestive problems. In such cases, treatment, such as medication or surgery, may be required.

Thus, the pylorus is an important organ for digestion and regulation of gastric acid secretion, and its dysfunction can lead to serious health consequences.

The pylorus or pyloric region is a specific anatomical zone of the stomach, responsible for the transition from the prostate of the stomach - a glandular mass saturated with food and blood - into the duodenum. The pyloric section has a height of 1 to 4 cm and a width of 3-4 cm. The wall of the stomach and the pyloric zone have unique protective properties. No function can function without the functioning of the gatekeeper.

The pylorus, also known as the pylorus or pyloric zone, is a section of the stomach that serves as a barrier between the “good” and “evil” zones. Biological substances have the ability to absorb excess food particles, as well as protect against bacteria and toxins. The pylorus is also important for the production of gastric juice and the breakdown of food into microelements. The pyloric part is an important part of the gastrointestinal tract. The lack of its functioning is no less dangerous than pyloric disease in adults, which is often observed. During the digestion of food, many useful substances are released along with hydrochloric acid. Acid substances make fats sticky and promote their absorption by the body. Therefore, it is important that inside the stomach,
