 carry the blood into the inferior vena cava (Fig. 156). 



The arterial blood supply of the liver is much smaller.

Liver cell from a dog. In the nucleus a haemoglobin crystal is to be seen ; in the

 the venous capillaries and some proceed as far as the centre of 

 the lobule to empty into the central vein. The capillary net-
