MESH:D001659 The path in many species is as follows: Bile canaliculi -> Canals of Hering (intralobar bile duct) -> 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 pancreatic duct -> forming ampulla of Vater -> enters duodenum [WP] FMA:14665 UBERON:0001173 uberon Hollow tree organ, the organ parts of which consist of the bile ducts.[AAO] Wikipedia:Biliary_tract biliary tract XAO:0000455 EMAPA:35172 UMLS:C0005423 interlobular bile duct intralobular bile duct gallbladder biliary system bile duct hepatobiliary system extrahepatic bile duct endoderm-derived structure biliary bud digestive system element
