Islet of Langerhans is located in which organ?

Islets of Langerhans are clusters of endocrine cells found within the pancreas. The pancreas contains both exocrine tissue (acini that secrete digestive enzymes) and endocrine tissue (the islets) that release hormones like insulin and glucagon directly into the bloodstream. Histologically, the islets appear as lighter, rounded clusters scattered among darker acinar cells. The thymus, liver, and spleen have other roles and do not contain these pancreatic endocrine islets. So, the correct organ is the pancreas.
