The science of functional anatomy divides the liver into left and right lobes based on their relation to the common bile duct, hepatic portal vein, and hepatic artery proper.
Oxygen is provided from both sources; about half of the liver's oxygen demand is met by the hepatic portal vein, and half is met by the hepatic arteries.

In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale.
right lobe of liver. The liver is divided into two lobes by the middle hepatic vein: the right lobe of liver and the left lobe of liver. The right lobe of liver is larger than the left lobe of ...
