Pancreatic islets Pancreatic islets The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (hormone-producing) cells, discovered in 1869 by German pathological anatomist Paul Langerhans. The pancreatic islets constitute 1 to 2% of the pancreas volume and receive 10–15% of its blood flow. The pancreatic islets are arranged in density routes throughout the human pancreas, and are important in the metabolism of glucose. There are about 3 million islets distributed in the form of "density routes" throughout the pancreas of a healthy adult human, each of which measures an average of about 0.1 mm (109
Trumpeter Islets pairs), short-tailed shearwater (1000 pairs), Pacific gull, silver gull, sooty oystercatcher, black-faced cormorant and Caspian tern. The Tasmanian tree skink is present. Trumpeter Islets The Trumpeter Islets comprise a group of two unpopulated islets, with a combined area of about a hectare, located close to the south-western coast of Tasmania, Australia. Situated some where the mouth of Port Davey meets the Southern Ocean, the island is part of the Trumpeter Islets Group, and comprises part of the Southwest National Park and the Tasmanian Wilderness World Heritage Site. The islets are part of the Port Davey Islands Important Bird Area, so
