Fig. 195. The origin of the portal vein and ductus venosus as illustrated by a human embryo of 7 mm
modified after Wilhelm His (1831-1904).
In the liver, the portal vein, through its cranial anastomosis between the primitive vitelline veins, is connected with the left umbilical vein (Fig. 195). As the right lobe of the liver grows, the course of the umbilical and portal blood through the intrahepatic portion of the right vitelline vein becomes circuitous, and hence a new, direct channel to the sinus venosus is formed through the hepatic sinusoids. This is the ductus venosus (Fig. 195), which is obliterated after birth and forms the ligamentum venosum of the postnatal liver.
