gyomorszáj

Gyomorszáj is the Hungarian term for the pylorus, which is the anatomical structure that marks the exit of the stomach and leads into the duodenum, the first part of the small intestine. It is a muscular sphincter that controls the passage of partially digested food, known as chyme, from the stomach into the small intestine. The pylorus plays a crucial role in regulating the rate at which the stomach empties.

The pylorus is comprised of smooth muscle tissue that forms a ring around the opening. When the stomach contracts, the pyloric sphincter relaxes, allowing chyme to move into the duodenum. Conversely, when the stomach is not actively digesting, or when the duodenum is full, the sphincter constricts, preventing backflow and holding food in the stomach for further digestion. This controlled emptying is essential for efficient nutrient absorption in the small intestine.

Disruptions to the normal function of the gyomorszáj can lead to various gastrointestinal issues. For instance, a condition called pyloric stenosis occurs when the pyloric sphincter becomes abnormally thickened, obstructing the passage of food. This is more common in infants. In adults, issues like peptic ulcers can sometimes affect the pylorus, and in some cases, surgery might be performed to address problems related to this region of the stomach.
