State that glucagon is secreted by the pancreas

Glucagon is a hormone secreted by the alpha cells of the pancreas. It plays a vital role in regulating blood glucose levels, particularly during periods of low blood sugar (hypoglycemia). When glucose levels drop, glucagon is released into the bloodstream, stimulating the liver to convert stored glycogen into glucose through a process called glycogenolysis. This action increases glucose availability in the blood, helping to restore normal blood sugar levels. Additionally, glucagon promotes gluconeogenesis, the synthesis of glucose from non-carbohydrate sources, further contributing to maintaining adequate glucose levels in the body.
