Enterogasterone is secreted by the epithelium which inhibits gastric secretion and morality.

Secretin is a digestive hormone secreted by the wall of the duodenum. Secretin helps regulate the pH of the duodenum by inhibiting the secretion of gastric acid from the parietal cells of the stomach and stimulates the acinar cells of the pancreas to secrete water and bicarbonate into the pancreatic ducts that drain into the duodenum. 

Enterocrinin is a hormone secreted by the duodenum mucosa and is stimulated by hydrogen ions which stimulates the intestinal glands to increase succus entericus juice. This breaks down sucrase, maltase, lactase, erepsin and nuclease for the body to use as energy.

cholecystokinin or CCK is a hormone released by stimulating endocrine cells by the fatty acids in the lumen of the duodenum. CCK or cholecystokinin role is to stimulate in smooth muscles of gallbladder and release of pancreatic secretions.

• Secretin is a hormone secreted by the small intestine on being stimulated by low pH. It stimulates the pancreas to release water and bicarbonate ions. These are then drained into the pancreatic duct.
