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 a large gland behind the stomach and next to the small intestine. The pancreas does two main things: 1  It releases powerful digestive enzymes into the small intestine to aid the digestion of food. 2  It releases the hormones insulin and glucagon into the bloodstream. 3  These hormones help the body control how it uses food for energy.
