Question

Quizplus · Accepted Answer

Secretin is a hormone secreted by cells in the duodenum in response to the presence of acid and lipids in the small intestine. Its primary function is to stimulate the secretion of bicarbonate from the pancreas, which helps neutralize the acidic chyme from the stomach as it enters the small intestine. Secretin also inhibits gastric acid secretion and promotes bile flow from the liver. While it may indirectly stimulate pancreatic enzyme secretion by providing a more favorable pH for enzyme activity, it does not directly stimulate pancreatic acinar cells.
