Hepatic artery divides into right and left branches . Right branch divides into anterior and posterior branches.Left branch divides into medial and lateral branches.
There are 3 main hepatic veins which drains into the Inferior vena cavaA 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.
