Secretin, the digestive hormone that stimulate pancreatic secretion, also increases bile secretion. Its main effect, however, is to increase the secretion of water and sodium bicarbonate from the lining of the bile duct.
The duodenum produces many hormones that help regulate digestion. Liver bile and pancreatic secretions are added to the bowel through the ampulla of Vater. The actual passage and presence of food in the duodenum starts the flow of hormones, bile and pancreatic secretions. By the time food leaves the duodenum most of the ingredients necessary for digestion have been added.
