What is Insulin?

Insulin is the hormone and it has a major role to regulate our blood glucose level. Insulin is secreted by the islets of  Langerhans cells of the pancreas. ( Particular B cells or Beta cells)

Whenever you eat the digested food breakdown down carbohydrates and this increases the blood sugar level in the bloodstream.

The increased level of blood sugar level activates the endocrine system and thus pancreas secretes Insulin. This Insulin helps to regulate blood sugar levels and stores sugar in the form of energy and fat in the body as well as in the lever also.

This stored fat can be used whenever energy is needed.  If the level of insulin reduces or production of insulin is stopped due to any cause it can lead to diabetes or an increase in blood sugar level.
