. Comparative anatomy. Anatomy, Comparative. HEPATIC VEIN B C and C—diagrams of successive stages in the development of the The subdivision of the Hver anlage into lobules is correlated with branching of the portal and hepatic veins. The branches of the hepatic vein are intralobular, and those of the hepatic portal vein—shown in black—are interlobular. (Redrawn after Mall.) Fig. 272.—A, B lobules of the liver. form the interlobular connective tissue which binds the lobules together. Bile capillaries appear within the cell cords, and the blood capillaries acquire endothelial walls. As a result of this, the lumen of each bile capillary is separated from that of each blood capillary by a layer of gland cells and a layer of endotheHal cells. (Figs. 261, 267, 272) The multiplication of tubular cords and of blood spaces results in a rapid enlargement of the liver, which begins to bulge out from the septum transversum and the ventral mesentery and to push into the abdominal cavity between the septum and the stomach. In this way, the liver becomes covered by the peritoneum and acquires its two chief lobes. The ventral mesentery into which it originally grew forms the falciform ligament. (Fig. 267).
