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.
The pancreas does two main things: 1  It releases powerful digestive enzymes into the small intestine to aid the digestion of food. 2  It releases the hormones insulin and glucagon into the bloodstream. These hormones help the body control how it uses food for energy.
