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. |
