Paul Langerhans

Paul Langerhans was a German physician and anatomist best known for discovering clusters of cells in the pancreas, now known as the islets of Langerhans. These cells play a crucial role in regulating blood sugar levels by producing hormones like insulin and glucagon. His work in the late 19th century significantly advanced our understanding of the endocrine system, which involves glands that release hormones into the bloodstream. The islets of Langerhans are vital for maintaining healthy metabolism and are central to conditions like diabetes, highlighting Langerhans' lasting impact on medicine and physiology.
