Human anatomy, including structure and development and practical considerations . about midway 108 1714 HUMAN ANATOMY. between the base and the opposite side of the lobule, Ijy the confluence of the capil-hiries, which, after the central vein is formed, upcn directly into the latter atlower planes. In those lobules which form part of the exterior of the liver thecentral vein ascends almost to the free surface ; otherwise its commencement isseparated from the i)eriphery by about one-half the thickness of the Icjbulc. Im-mediately on emer^ini; from the lobule the central vessel opens int(j the sublohuhn-vein, which runs generally at right angles to its intralobular tubularies and along andbeneath the bases of the lobules, the outlines of which are often seen through thewalls of the vein. The channels for the sublobular veins are thus surrounded bythe bases of the lobules, a single central vein returning the blood from each. The Fig. 1446.

The Liver-Cells.—The meshes of the interlobular capillary net-work are oc-cupied by the hepatic cells, the bile-capillaries, and a meagre amount of connectivetissue. The cells are arranged as cords or trabecuke which conform in their generaldisposition to the intcrcapillarv spaces, which they completely fill.
