The persisting left umbilical vein travels from the placenta to enter the foetal abdomen at the umbilicus and courses into the liver. Within the liver, oxygenated blood passes through the ductus venosus to enter the left hepatic vein near its confluence with the IVC.
What is difference between placenta and umbilical cord?
The placenta is a large organ that develops during pregnancy. It is attached to the wall of the uterus, usually at the top or side. The umbilical cord connects the placenta to your baby. Blood from the mother passes through the placenta, filtering oxygen, glucose and other nutrients to your baby via the umbilical cord.

How do you know umbilical vein?
Two thick-walled small arteries and one thin-walled larger vein should be identified (see the images below).
