Final answer:
The pancreas releases insulin and glucagon, which are key hormones in blood glucose regulation. Insulin is produced by beta cells and glucagon by alpha cells, while somatostatin from delta cells inhibits both their secretions.
Step-by-step explanation:
The hormone released from the pancreas is insulin. Another major hormone secreted by the pancreas is glucagon.
The pancreas plays a crucial role in glucose metabolism. The beta cells of the pancreatic islets produce insulin, which is released in response to elevated blood glucose levels. In contrast, alpha cells release glucagon when blood glucose levels are low, helping to maintain glucose homeostasis. The delta cells of the pancreas secrete somatostatin, which inhibits the release of both glucagon and insulin, thereby regulating the functions of other pancreatic hormones. The pancreas also houses PP cells that secrete the pancreatic polypeptide hormone, which can influence appetite and the regulation of both exocrine and endocrine secretions of the pancreas.
