What is the pancreas and what does it do?

The pancreas is a fish-shaped organ (with a head to the right and tail to the left) which lies behind the stomach. It is made up of two types of cells:

1. Exocrine cells: These cells produce a pancreatic juice that includes enzymes which aid in the digestion of food in the small intestine, breaking up proteins,carbohydrates and fats.
2. Endocrine cells: These are clustered in small groups (called the Islets of Langerhans)scattered throughout the pancreas. These cells produce important hormones such as insulin, glucagon, and somatostatin.
