Question

Quizplus · Accepted Answer

Secretin is a hormone that is produced in the duodenum in response to the presence of acid. Its main function is to stimulate the secretion of bicarbonate from the pancreas and the liver. This helps to neutralize the acid and maintain the pH of the small intestine in the normal range. Secretin does not stimulate the secretion of pancreatic enzymes or the acinar cells. Furthermore, it is not specifically stimulated by the presence of fat in the duodenum.
