The exocrine function of the pancreas is involved in digestion, and these associated structures are known as the pancreatic acini. The pancreatic acini are clusters of cells which produces digestive enzymes and secretions and make up the bulk of the pancreas. The endocrine function of the pancreas is to help in maintaining blood glucose levels, and the structures involved are known as the pancreatic islets, or the islets of Langerhans.
