The pancreas produces (in addition to others) two important hormones, insulin and glucagon. They work together to maintain a steady level of glucose, or sugar, in the blood and to keep the body supplied with fuel to produce and maintain stores of energy.
|Secreted hormone||From cells||Effect|
|Insulin (Primarily)||β Islet cells||Intake of glucose, glycogenesis and glycolysis in liver and muscle from bloodintake of lipids and synthesis of triglycerides in adipocytes Other anabolic effects|
|Glucagon (Also Primarily)||α Islet cells||glycogenolysis and gluconeogenesis in liverincreases blood glucose level|
|Somatostatin||δ Islet cells||Inhibit release of insulin
Inhibit release of glucagon Suppress the exocrine secretory action of pancreas.
|Pancreatic polypeptide||PP cells||Self regulate the pancreas secretion activities and effect the hepatic glycogen levels.|
