The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells. Discovered in 1869 by German pathological anatomist Paul Langerhans, the pancreatic islets constitute approximately 1-2% of the pancreas's mass and receive 10-15% of its blood flow.here are about one million islets distributed throughout the pancreas of a healthy adult human, :914 each of which measures about 0.2 mm in diameter.
PancreasâIslets of Langerhans. 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.he 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.
