Cunningham's Text-book of anatomy cunninghamstextb00cunn Year: 1914 ( VESSELS OF THE LIVER. 1199 number of thorns growing out on all sides from the sublobular twigs of the tree). On each of these little central veins there is impaled, as it were, a lobule. These little conical lobules, with their central veins running through them, are so numerous and so closely packed together, that they give rise to the practically solid liver tissue. The lobules are surrounded by the vense interlobulares, branches of the portal vein, from which numerous twigs enter the lobule on all sides, and converging, join the central vein (Fig. 940). This runs through the centre of the lobule (Fig. 941, A), and opens at its base into a sublobular vein. The sublobular veins, uniting and growing larger by constant additions, finally form the hepatic veins, which open into the vena cava. Hepatic Cells.—In the intervals between the branches of the capillaries, running from the interlobular to the central veins (Fig. 940), are placed the polygonal-shaped epithelial, hepatic cells. Between the cells run the ductus biliferi ( bile canaliculi) which, passing out of the lobule (Fig. 941), join the ductus interlobulares, and these uniting, finally end in the hepatic ducts. The liver cells are very intimately connected both with the blood capillaries and the radicles of the bile-ducts. From both sets of vessels minute channels pass into the interior of the hepatic cells, forming intracellular canals. The blood plasma is thus brought into very intimate relation with the plasma of the hepatic cells, and the small fine intracellular biliary canaliculi facilitate the secretion of bile by the cells. Vessels of the Liver. Like many other glands, the liver presents, as has been seen, a hilus, or slit-like fissure, upon its surface, where vessels are found, and where the ducts emerge. In the liver, the hilus is placed upon the inf
