WitrynaThe endocrine portion consists of the pancreatic islets, which secrete glucagons and insulin. Alpha cells in the pancreatic islets secrete the hormone glucagons in response to a low concentration of glucose in the blood. Beta cells in the pancreatic islets secrete the hormone insulin in response to a high concentration of glucose in the blood. The paracrine feedback system of the pancreatic islets has the following structure: • Glucose/Insulin: activates beta cells and inhibits alpha cells. • Glycogen/Glucagon: activates alpha cells which activates beta cells and delta cells. • Somatostatin: inhibits alpha cells and beta cells. Also inhibits the secretion of pancreatic polypeptide.
