Structure
The pancreas is a digestive organ that lies below the stomach, it is mostly made up of exocrine and endocrine tissues. The exocrine parts form sacs known as Acini, which connect to ducts with empty into the first part of the intestine (The duodenum). Smaller parts of the exocrine glands are dispersed all throughout the pancreas which are known as islets of Langerhans (Anon, Unknown).

Function
The main function of the pancreas is maintaining blood glucose levels to about 70-150 milligrams per decilitre. The pancreas does this by measuring if the blood sugar level is too high or low, if it is not the correct level then a hormone is released. If the blood sugar level is too high insulin is released from the beta cells and causes glucose to enter body cells to be used for energy but sometimes can stimulate glucose to turn to glycogen in the liver. However, if it is too low then glucogen is released into the blood which causes the stored glycogen in the liver to break down
