The pancreas produces glucagon.
Understanding Glucagon and the Pancreas
Glucagon is a crucial hormone that helps regulate blood sugar levels. It's produced by specialized cells within the pancreas called alpha cells. The pancreas itself is a vital organ with a dual role:
- Exocrine function: Producing enzymes essential for digestion. These enzymes are released into the small intestine to break down food.
- Endocrine function: Producing and releasing hormones, including glucagon and insulin, directly into the bloodstream. This endocrine function is key to maintaining blood glucose balance.
The alpha cells within the islets of Langerhans (clusters of hormone-producing cells in the pancreas) are responsible for synthesizing and secreting glucagon. When blood sugar levels drop, glucagon signals the liver to release stored glucose, raising blood sugar back to normal levels. This process is essential for maintaining energy levels and overall metabolic health.
The reference clearly states: "Glucagon is produced by the alpha cells of an organ called the pancreas."
