Glucagon, a crucial hormone regulating blood sugar levels, is produced in the alpha cells located within the islets of Langerhans in the pancreas. These specialized clusters of cells within the pancreas are responsible for secreting several important hormones.
The Pancreas and Glucagon Production
The pancreas, a vital organ in the digestive system, plays a dual role: it produces digestive enzymes and hormones. Within the pancreas, the islets of Langerhans house different cell types, each producing a unique hormone. Alpha cells, specifically, are dedicated to glucagon synthesis and release.
When blood sugar drops too low (hypoglycemia), the alpha cells detect this change and release glucagon into the bloodstream. This hormone then signals the liver to break down stored glycogen (a form of glucose) and release it into the circulation, raising blood glucose levels to restore balance.
Detailed Location: Alpha Cells within Islets of Langerhans
To reiterate:
- Organ: Pancreas
- Specific Cell Type: Alpha cells
- Location within Pancreas: Islets of Langerhans
This precise location ensures efficient interaction with other pancreatic hormones, like insulin, to maintain tight control over blood glucose homeostasis.
