The pancreatic duct or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct) is a duct joining the pancreas to the common bile duct. This supplies it with pancreatic juice from the exocrine pancreas , which aids in digestion .
The biliary tree (see below) is the whole network of various sized ducts branching through the liver.. The path is as follows: bile canaliculi → canals of Hering → interlobular bile ducts → intrahepatic bile ducts → left and right hepatic ducts merge to form → common hepatic duct exits liver and joins → cystic duct (from gall bladder) forming → common bile duct → joins with ...
The ductal pancreas network originates from the central pancreatic duct—this main duct with the bile duct opens into the duodenum. The ductal cells of the main pancreatic duct are bound by connective tissue and produce a columnar epithelium. [3] Interlobular ducts originate from the main pancreatic duct and connect the various pancreatic lobes.
Two ducts, the main pancreatic duct and a smaller accessory pancreatic duct run through the body of the pancreas. The main pancreatic duct joins with the common bile duct forming a small ballooning called the ampulla of Vater (hepatopancreatic ampulla). This ampulla is surrounded by a muscle, the sphincter of Oddi.

The isthmus (also called the central pancreas) is the region of the gland that runs anterior to the superior mesenteric artery; by convention, it divides the right and left sides of the pancreas. [2] The ventral pancreatic bud forms the pancreatic head and uncinate process. The glands continue to develop but the duct systems anastomose.

These lobular ducts finally converge to form the main pancreatic duct. [1] These pancreatic ducts can act as a response mechanism when injury occurs and to avoid disruptions in the pancreatic lumen. [3] This keeps the ionic content in check while keeping it open for flow to occur. Mutations that can occur because of blockage/ accumulation in ...
