FIG. 199. Cross-section of a lobule of the human liver, in which the capillary network between 

 the portal and hepatic veins has been fully injected. 1, section of the mfra-lobular vein; 2, its smaller 

 branches collecting blood from the capillary network; 3, tnfer-k>bular branches of the vena portre 

 with their smaller ramifications passing inward toward the capillary network in the substance of 

 the lobule, x 60. (Sappey.) 



FIG. 200. Section of a portion of liver passing longitudinally through a considerable hepatic vein, 

 from the pig. H, hepatic venous trunk, against which the sides of the lobules (I) are applied; /i, 7i, 7i, 

 sublobular hepatic veins, on which the bases of the lobules rest, and through the coats of which they 

 are seen as polygonal figures; t, mouth of the intralobular veins, opening into the sublobular veins; 

 i', intralobular veins shown passing up the centre of some divided lobules; I, I, cut surface of the 

 liver; c, c, walls of the hepatic venous canal, formed by the polygonal bases of the lobules. X 5.

 of the liver to end by two or three principal trunks in the interior vena
