The pancreas has two functions. It plays a major role in digestion, releasing enzymes that break down fat, starch, and proteins through the pancreatic ducts into the intestine. It also contains clusters of cells, called islets of Langerhans, that secrete hormones directly into the bloodstream. These cells secrete insulin and glucagon, two hormones that regulate glucose levels in the body, and other digestive hormones.
