Dissection of left lobe of liver, viewed from left
The left lobe of the liver has been cut in a saggital plane parallel to the falciform ligament. The interior of the lobe has been dissected to display branches of the hepatic artery, hepatic duct and portal vein ensheathed in a common layer of fibrous tissue (6). These structures comprise the portal triad and occupy an interolobular position. Tributaries of one of the hepatic veins (1), centrally located with respect to the lobules, also may be traced in the dissection. These converge toward the vena cava and are better seen in later stages of the dissection. The extension of the lesser omentum (20) into the depths of the fissure of the ligamentum venosum is illustrated.
