ANATOMY

Detailed explanation-1: -Glucagon is a hormone that your pancreas makes to help regulate your blood glucose (sugar) levels. Glucagon increases your blood sugar level and prevents it from dropping too low, whereas insulin, another hormone, decreases blood sugar levels.

Detailed explanation-2: -When blood glucose levels fall too low (low blood glucose), the pancreas pumps out more glucagon. This hormone helps blood glucose rise back up in multiple ways: It causes the liver to convert stored glucose into a usable form and then release it into the bloodstream. (A process called glycogenolysis.)

Detailed explanation-3: -Glucagon is a glucoregulatory peptide hormone that counteracts the actions of insulin by stimulating hepatic glucose production and thereby increases blood glucose levels.
