Introduction
The pancreas has exocrine and endocrine functions. The exocrine part secretes pancreatic juice; a solution containing enzymes for carbohydrate, protein and triacylglycerol digestion. Pancreatic juice drains into the small intestine where it is functional. The exocrine part is the larger of the two parts of the pancreas. The endocrine part secretes hormones for the regulation of blood glucose concentration, including insulin, glucagon and somatostatin. The functional units of the exocrine part are the islet of Langerhans.
