The bile flows directly from the liver through the (hepatic) bile duct into the small intestine (Hebel and Stromberg, 1988) TAO:0000208 The presence of a gallbladder appears to be a primitive trait. It is found in most fish and all adult reptiles and amphibians and has been well conserved in mammals, for the most part.[well established][VHOG] UBERON:0002110 UMLS:C0016976 VHOG:0000221 XAO:0000135 ZFA:0000208 galen:Gallbladder gall bladder gallbladder relationship type change: differentiates_from endoderm (AAO:0000139) CHANGED TO: develops_from endoderm (UBERON:0000925)[AAO] uberon vesica biliaris vesica fellea coelemic cavity lumen hepatobiliary system endoderm-derived structure biliary bud gall bladder primordium digestive system element abdominal viscera bladder organ
