Why is insulin required by the body
Insulin and Glucagons are hormones that regulates the level of
glucose in the blood. Insulin is secreted by the pancreas, an endocrine gland
located in the abdomen. Pancreas is made up of two types of tissue: exocrine
and endocrine. The endocrine tissue consists of specialised tissue known as the
islets of Langerhans that produce insulin and glucagons. The pancreas secretes
insulin in small amounts, but when there is a rise in the blood glucose level
the amount of secretion increases to control it. On the other hand, glucagons
are secreated when the sugar level in the blood is low. It helps to increase
the sugar level in the blood.
