The pancreas produces digestive juices and insulin, as well as other hormones to do with digestion. The part which produces the digestive juices is called the exocrine pancreas. The part which produces hormones, including insulin, is called the endocrine pancreas. The digestive system breaks up and digests food. After about 2 hours in the stomach, the partly digested food moves into the beginning of the duodenum.
When the food reaches the duodenum, the pancreas releases its digestive juices which flow down the pancreatic duct and mix with the food. The juices contain enzymes that help to break down the food into very small fragments.
These fragments are absorbed into the body through the small bowel. The pancreas makes insulin. Disclaimer: This article is for information only and should not be used for the diagnosis or treatment of medical conditions.
