Gastrin is a hormone produced by the stomach which plays an important role in digestion It stimulates the secretion of gastric juices and the release of hydrochloric acid from the parietal cells in the stomach, which helps to break down food in the digestive system. Gastrin also helps to regulate the size of the pyloric sphincter, which is a muscular ring that controls the opening and closing of the stomach into the duodenum (small intestine). In addition, it is involved in the regulation of the secretion of bile and pancreatic juices, and helps to maintain the correct pH balance in the stomach.
