CROSS-SPECIES ANATOMY - ANNOTATIONS

The Basic subset of the UBERON integrated, cross-species anatomy ontology is downloaded weekly from http://berkeleybop.org/ontologies/uberon/basic.obo. For more information about this ontology see the "About" page on the UBERON website at http://uberon.github.io/about.html.

Definition:A complex network of conduits that begins with the canals of Hering (intralobar bile duct) and progressively merges into a system of interlobular, septal, and major ducts which then coalesce to form the extrahepatic bile ducts, which finally deliver bile to the intestine, and in some species to the gallbladder.
Comment: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]
