Endocrine story of pancreas ,endocrine secreation is through ductless gland
Pancreas is the only gland which has both endocrine and exocrine function digestive enzymes produced.Through ducts .
Pancreas is digestive gland weight about half a pound located just below and behind stomach . The pancreas shows lobular structure . Endocrine group of cells called islet of
Langerhans . The islet of Langgerhans make about 1% of pancreas . Normal pancreas has 1000000 islets of Langerhans and each islet has 80 - 100 beta cells . These cells can measure the blood glucose every 10 seconds ,within minutes to minute and half the beta cells can deliver the exact amount of insulin needed to keep blood glucose levels normal .
Alpha cells produce glucagon hormone .Delta cell to carry message between insulin and gluucogon.

The Role of Insulin :
The carbohydrate in our food are digested in the intestine the end products of carbohydrates are various sugars chiefly glucose . This glucose is absorbed through the mucous membrane of intestine to enter blood stream .Thus concentration of glucose in blood rises .Insulin makes this glucose available to each and every cell of our body .Like visa gives entry to foreigner to entry in foreign country.If insulin is inadequate or absent the glucose in blood cannot enter various body cells or cannot be converted in to glycogen consequently blood glucose rises. Diabetes is the final result.
