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 ...
