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 blood in the small intestine also carries the nutrients from food to the rest of the body. The small intestine gets enzymes from two important glands, called the liver and the pancreas. The liver is the largest organ in our bodies. It makes a liquid called bile that helps digest fat. The bile is stored in another organ called the gall bladder.
