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.
The pancreas is the organ responsible for making and secreting digestive enzymes. Oral digestive enzymes are used when the pancreas is unable to produce enough digestive enzymes. The main digestive enzymes are. 1  proteases for digesting proteins, 2  lipases for digesting fats, and. 3  amylases for digesting carbohydrates.
