MICROANATOMY

Detailed explanation-1: -The pancreas is solid (acinar tissues), and contains drainage tubes (the pancreatic ductal system). The pancreatic juices are made in the acinar tissues, and passed by secretion into the tubes (ducts) for transport into the duodenum. The exit hole into the duodenum is called the papilla of Vater.

Detailed explanation-2: -Pancreatic juice is composed of two secretory products critical to proper digestion: digestive enzymes and bicarbonate. The enzymes are synthesized and secreted from the exocrine acinar cells, whereas bicarbonate is secreted from the epithelial cells lining small pancreatic ducts.

Detailed explanation-3: -The exocrine cells (acinar cells) of the pancreas produce and transport chemicals that will exit the body through the digestive system. The chemicals that the exocrine cells produce are called enzymes. They are secreted in the duodenum where they assist in the digestion of food.
