A hormone called glucagon is important in regulating blood sugar (glucose) levels. It is synthesized by alpha cells and then released into the bloodstream from the pancreatic islets of Langerhans.
When blood glucose levels are too low, the pancreas releases more glucagon into the body (low blood glucose). In numerous ways, this hormone aids in the recovery of blood glucose: As a result, the liver releases glucose into the bloodstream after converting stored glucose into a usable form. Alpha cells in the islets of Langerhans secrete glucagon, and beta cells secrete insulin. The hormones insulin and glucagon control the body's glucose level to maintain it within a healthy range.
We can therefore conclude that glucagon, a hormone, is crucial for controlling blood sugar (glucose) levels. The pancreatic islets of Langerhans' alpha cells are responsible for their production.
