The pancreas provides two main functions which are physiologically dissimilar as follows
Enymes for digestion
The endocrine function of the pancreas include the production of hormones such as insulin. Special cells aggregate together in islands to form what are called islets of Langerhans. These islets are ductless but are also highly vascularized. Their secretions are discharged directly into the blood stream. The cells which are endocrine cells are of four major groups.
1. A cells which produce glucagon.
2. B cells which produce insulin
3. PP cells which produce pancreatic polypeptide
4. B cells which produce somatostatin
