GENERAL HISTOLOGY

Detailed explanation-1: -The pancreatic duct runs obliquely through the wall of this part of the duodenum, opening on eminence, called the major duodenal papilla. On the right of pancreatic head, the pancreatic duct usually unites to the common bile duct to form the hepatopancreatic ampulla, which opens at the major duodenal papilla.

Detailed explanation-2: -The ventral duct persists as the main pancreatic duct (duct of Wirsung) which drains into the duodenum via the ampulla of Vater (major papilla). The dorsal duct becomes the accessory pancreatic duct (duct of Santorini) which drains via the minor (accessory) papilla.

Detailed explanation-3: -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-4: -Most pancreatic duct contents are released into the duodenum at the major duodenal papilla.

Detailed explanation-5: -The common bile duct passes through the pancreas before it empties into the first part of the small intestine (duodenum). The lower part of the common bile duct joins the pancreatic duct to form a channel called the ampulla of Vater or it may enter the duodenum directly.
