Verified step by step guidance

Understand the role of glucagon: Glucagon is a hormone that plays a crucial role in regulating blood glucose levels by promoting the release of glucose from the liver into the bloodstream.

Identify the location of glucagon secretion: Glucagon is secreted by the pancreas, specifically from the islets of Langerhans, which contain different types of cells responsible for hormone production.

Differentiate between the types of cells in the islets of Langerhans: The islets contain several types of cells, including alpha cells, beta cells, delta cells, and gamma cells, each with distinct functions.

Focus on alpha cells: Alpha cells are responsible for secreting glucagon. They respond to low blood glucose levels by releasing glucagon to increase glucose availability.

Review the functions of other cell types: Beta cells secrete insulin, which lowers blood glucose levels. Delta cells produce somatostatin, which regulates the secretion of other hormones. Gamma cells are less commonly discussed but are involved in pancreatic polypeptide secretion.
