Role in the Endocrine System: ,[object Object],Secreted by pancreatic beta cells, insulin signals the body to remove glucose from the bloodstream, therefore lowering blood sugar levels. This happens after meals, when new carbohydrates are absorbed by the body. This process is important for cellular respiration, in which cells require glucose. Glucagon is secreted by pancreatic alpha cells and performs the opposite function of insulin. It causes glycogen stored in the liver to be broken back down into glucose, which is then released into the bloodstream to raise blood sugar. This occurs during the beginning of hard exercise or if a meal has not been eaten for several hours. In these instances, the body needs more sugar to function.
