The endocrine part of pancreas is known as Islet of Langerhans which is a group of different types of cells.
- Alpha cells produce, stores and secretes hormone glucagon. It regulates blood glucose, in case low blood glucose levels it stimulate release of glucose in the blood.
- Beta cells produce, store and secrete hormone insulin. It regulates blood glucose, in case high blood, it decrease blood glucose level and Store glucose in the form of glycogen in liver and muscles.
