The small intestine is where most chemical digestion takes place. Most of the digestive enzymes in the small intestine are secreted by the pancreas and enter the small intestine via the pancreatic duct. These enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in response to the presence of nutrients.
Secretin is a digestive hormone secreted by small intestine. Secretin causes the pancreas to release digestive enzymes which break down food and help the body absorb nutrients. Secretin inhibits gastric acid secretion.
