The liver is made up of small roundish or oval portions called lobules, each of which is composed of minute branches of the portal vein, hepatic artery, hepatic duct, and hepatic vein. Shown is the capillary network of the lobules of the rabbit's liver. The figure is taken from a very successful injection of the hepatic veins showing nearly the whole of two lobules, and parts of three others. Labels: p, portal branches running in the interlobular spaces; h, hepatic veins penetrating and radiating from the center of the lobules.

Hepatic cells and bile capillaries, from the liver of a child three months old. Both figures represent fragments of a section carried through the periphery of a lobule. The red corpuscles of the blood are recognized by their circular contour; vp, corresponds to an interlobular vein in immediate proximity with which are the epithelial cells of the biliary ducts, to which , at the lower part of the figures, the much larger hepatic cells suddenly succeed.

Section of a portion of liver passing longitudinally through a considerable hepatic vein, from the pig. Labels: H, hepatic venous trunk, against which the sides of the lobules (l) are applied; h, sublobulour hepatic veins, on which the bases of the lobules rest, and through the coats of which they are seen as polygonal figures; i, mouth of the intralobular veins, opening into the sublobular veins; i', intralobular veins shown passing up the center of some divided lobules; l, cut surface of the liver; c, walls of the hepatic venous canal, formed by the polygonal bases of the lobules.
