Beta cells (Î²-cells). Beta cells are a type of cell in the pancreas located in the so-called islets of Langerhans. They make up 65-80% of the cells in the islets. The Islets diameter is about 50 to 300 micrometers. They are composed of several types of cells. At least 70 percent are beta cells, which are localized in the core of the islet.
There are 2 main types of endocrine cells that make up the islets: alpha cells and beta cells. Alpha cells produce the hormone glucagon, which raises blood glucose levels. Beta cells produce the hormone insulin, which lowers blood glucose levels. Physiology of the Pancreas Digestion. The exocrine portion of the pancreas plays a major role in the digestion of food.
