pilórica

Pilórica refers to the pylorus, which is the lower part of the stomach that connects to the duodenum, the first section of the small intestine. This muscular sphincter plays a crucial role in digestion by regulating the passage of partially digested food, known as chyme, from the stomach into the small intestine. When the stomach contracts, the pyloric sphincter relaxes, allowing chyme to move through. Conversely, it tightens to prevent the backflow of intestinal contents into the stomach. The pyloric region itself is characterized by a thickened layer of smooth muscle, which enables its effective functioning as a valve. Conditions affecting the pylorus include pyloric stenosis, a narrowing of the opening that can impede food passage, and pyloric ulcers, which are sores that can develop in the lining of this part of the stomach. These issues can lead to symptoms such as vomiting, abdominal pain, and difficulty gaining weight, particularly in infants for pyloric stenosis.
