*Functional units are the islets of Langerhans, which are embedded throughout the exocrine tissue.
*Functional units are the islets of Langerhans, which are embedded throughout the exocrine tissue.
*Production of hormones that maintain normoglycaemia.
*Cells of the islets produce hormones that maintain normoglycaemia.
*There are ''four'' different cell types within each islet that each produce different hormones.
**α cells produce '''glucagon'''
**β cells produce '''insulin'''
**δ cells produce '''somatostatin'''
**F cells produce '''pancreatic polypeptide'''
**Glucagon is released when blood glucose levels are low
**Insulin
**Somatostatin acts in a paracrine fashion to inhibit both glucagon and insulin secretion.
