Beta cell

From WikiMD's Food, Medicine & Wellness Encyclopedia

Pancreatic islets, also called islets of Langerhans, are groups of cells in your pancreas. The pancreas is an organ that makes hormones to help your body break down and use food in a process called digestion.

Pancreas[edit | edit source]

The pancreas is a long, soft organ that lies transversely along the posterior abdominal wall, posterior to the stomach, and extends from the region of the duodenum to the spleen. This gland has an exocrine portion that secretes digestive enzymes that are carried through a duct to the duodenum. The endocrine portion consists of the pancreatic islets, which secrete insulin.

Beta cells[edit | edit source]

Islets contain several types of cells, including beta cells that make the hormone insulin. Insulin helps your body use glucose for energy and helps control your blood glucose levels, also called blood sugar.

Alpha cells[edit | edit source]

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.
