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.
The pancreas is made up of 2 types of glands: Exocrine. The exocrine gland secretes digestive enzymes. These enzymes are secreted into a network of ducts that join the main pancreatic duct, which runs the length of the pancreas.
