Capillary Network in the Lobules of a Rabbit's Liver
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.
