As for the hepatic and portal veins, their branching patterns were observed after cutting open their vessel walls. For the bile duct, its connection between the hepatic duct and duodenum was traced. For reference, the marbled eel, A.marmorata, was used especially to recognize its detailed relation of branches of the coeliac artery. Each restoraion was done conerning with above mentioned vascular system by drawing its external feature. As results, branching number of the right side of the hepatic vein is less than that of the left side and the same or approximate as in the portal vein. Divided typed branches which go towards the left lobe of the liver after deriving from the portal vein pass below the hepatic vein. Their number is approximately same as that of the right branches of the hepatic vein. Hepatic artery derives from the coeliac artery. It sends mono- or divided typed branches to the anterior hepatic parenchyma on its way and later penetrates into the latter. The other routes to the liver are recognized as two branches of the gastric artery which derives from the coeliac artery. They distribute on the posterior parenchyma of the liver. Bile duct is composed of the hepatic and choledochal ducts, the former sends out two to four branches to the parenchyma and connects itself to the latter. The latter opens to the duodenum, being enveloped in the ODDI's sphincter. The gall bladder connects through the cystic duct with the hepatic duct.}, pages = {113--124}, title = {Anatomy of the Hepatic Vascular System of the Eel, A. japonica}, volume = {31}, year = {} }
