MICROANATOMY

Detailed explanation-1: -Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream. This process is called glycogenolysis. Glucagon can also prevent your liver from taking in and storing glucose so that more glucose stays in your blood.

Detailed explanation-2: -Glucagon, in part, triggers glycogen in your liver to convert back to glucose so it can enter your bloodstream. This process is called glycogenolysis. When glucose is in your bloodstream, cells throughout your body can use it for energy.

Detailed explanation-3: -Glucagon’s role in the body is to prevent blood glucose levels dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream.

Detailed explanation-4: -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-5: -Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.
