6. Arterial Supply
- Hepatic artery: Liver receives 20% of its blood supply from hepatic artery. This is oxygenated blood.
- Portal vein: Liver receives 80% of its blood supply from portal vein. This is nutrient-rich venous blood
7.Venous Drainage: Hepatic sinusoids drain into interlobular veins, which join to form sublobular veins. These in turn unite to form the hepatic veins which drain directly into the inferior vena cava
8. Nerve Supply: Sympathetic fibres that are derived from the coeliac plexus. They run along the vessels in the free margin of the lesser omentum and enter the porta hepatis.
Parasympathetic fibres that are derived from hepatic branch of the anterior vagal trunk
