Abstract: Objective To provide the morphological data for diagnosis and treatment of the liver diseases by observation of the anatomical properties and embranchment of the right portal branches. Methods Fifty non-illness by visual study adult cadaveric livers were anatomied, embranchment of the right portal branches was observed, the main trunk of right portal branches and correlated data were measured and analyzed statistically. Results Totally 82% appeared right and left branch distribution of the portal vein， the angulation was（105.59±13.82）°,there were 5 types for right portal vein，65.8％there were posterior segmental and anterior segmental branch of right stems. There are 6 types for posterior segmental branch of right stems which provide Couinaud 6，7 segment, but 6.0％ portion of 6 segment provided by anterior segmental branch, 2.0％ the whole come from anterior segmental branch. The anterior segmental trunk provide 5，8 segment, 36.0％ 5 segment provided by posterior segmental, 6.0％ anterior segmental branch to 4 segment.Conclusion There are many types for right branc
