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.
Pancreas. The pancreas is a long, thin gland that lies horizontally behind the bottom part of your stomach. It makes digestive enzymes that flow through the pancreatic duct to the small intestine. These enzymes, along with bile from the gallbladder, break down food for use as energy by the body. The pancreas also makes insulin and glucagon, hormones that help regulate blood glucose (sugar) levels.
