MICROANATOMY

Detailed explanation-1: -Glucagon is a peptide hormone secreted from the alpha cells of the pancreatic islets of Langerhans. Hypoglycemia is physiologically the most potent secretory stimulus and the best known action of glucagon is to stimulate glucose production in the liver and thereby to maintain adequate plasma glucose concentrations.

Detailed explanation-2: -When your blood glucose levels trend lower or fall too low (hypoglycemia), your pancreas releases more glucagon. Glucagon helps blood glucose levels rise back up in multiple ways, including: Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

Detailed explanation-3: -The most important hormone that the pancreas produces is insulin. Insulin is released by the ‘beta cells’ in the islets of Langerhans in response to food. Its role is to lower glucose levels in the bloodstream and promote the storage of glucose in fat, muscle, liver and other body tissues.
