Pancreas: A large, elongated gland lying transversely behind the stomach, between the spleen and duodenum. Its external secretion contains digestive enzymes. One internal secretion, insulin, is produced by the beta cells, and another, glucagon, is produced by the alpha cells. Chapter Review. The pancreas has both exocrine and endocrine functions. The pancreatic islet cell types include alpha cells, which produce glucagon; beta cells, which produce insulin; delta cells, which produce somatostatin; and PP cells, which produce pancreatic polypeptide. The focus of this gastrointestinal anatomy and physiology course is to teach you about the structures and functions of the gastrointestinal system and its accessory organs. The anatomical structures of the gastrointestinal system work together to achieve three major goals.

Chapter Review. The pancreas has both exocrine and endocrine functions. The pancreatic islet cell types include alpha cells, which produce glucagon; beta cells, which produce insulin; delta cells, which produce somatostatin; and PP cells, which produce pancreatic polypeptide. The two major cell types of the exocrine pancreas are the acinar cell and the ductal cell. The acinar cells are formed into a unit called the acinus which is connected to the ductal system composed of ductal cells (Figure 3). 4 digestive enzymes into the duodenum where digestion is initiated.
