4. 2 anatomical lobes -right and left
Right lobe further divided into caudate lobe on the
posterior surface and quadrate lobe on the inferior surface.
A fold of peritoneum called falciform ligament separates

8. Blood supply
Liver receives about 70% of its blood supply via the
portal vein and 30% from the hepatic artery.
Hepatic artery divides into right and left branches .
Right branch divides into anterior and posterior
branches.
Left branch divides into medial and lateral branches.

10. There are 3 main hepatic veins which drains into the
Inferior vena cava
A large central vein runs between the right and left
halves of the liver and receives blood from each.
Then right and left veins which lie further lateral to
the central vein.
