ABSTRACT
Vascular systems entering into liver tissue consist of two types, one via regular hepatic arteries and another via portal vein downstream of intestinal blood vessels (Moore, 1988; Gilbert, 1988). Both connect to liver-specific networks called “sinusoidal capillaries” which are unique characteristics of the liver. Based on the main function of the liver in which nutrients obtained from foods in intestines are absorbed and metabolized in hepatic cells, the major route of the blood stream into liver is through the portal vein.
