Hepatic Veins

Hepatic veins in the human body are the blood vessels that carry deoxygenated blood from the liver and the blood cleaned by liver (from pancreas, stomach, colon and small intestine) to the inferior vena cava.

The veins begin from the substance of the liver, exactly the central vein of the liver lobule. Hepatic veins do not have any valves. The hepatic veins can be categorized in two groups that is the upper group and lower group.

• The upper group starts from the posterior aspect of the liver. There are three in number and they are responsible for draining quadrate lobe and left lobe.
• The lower group starts from the right lobe and caudate lobe. They can be varying in number and smaller than the ones in upper group.
