The hepatic veins then serve as the sole *outflow* conduit for this processed blood. The hepatic veins form the primary venous drainage system of the liver, responsible for transporting blood away from the organ back to the heart.
Hepatic Veins: The Liver's Primary Outflow Drainage System
Variations in the number, size, and insertion points of these veins are common and must be meticulously identified to preserve venous outflow and prevent ischemic damage to the remaining liver remnant. The hepatic arteries supply oxygenated blood.
These veins originate within the liver parenchyma, collect blood from the hepatic sinusoids, and converge as they exit the liver capsule near the porta hepatis. Understanding this pathway is fundamental to comprehending liver physiology and the systemic circulation.

Anatomy of Hepatic Vein Drainage Unlike many organs with a singular main vein, the liver utilizes a tripartite venous system. Clinical Significance and Pathologies Disorders affecting hepatic venous drainage can have severe systemic consequences.
