The 9 region abdominal anatomical scheme uses the vertical midclavicular lines and horizontal transpyloric and transtubercular planes to divide the abdomen into 9 regions
Anterior and posterior views of the liver
The green lines highlight Cantlie's line, a vertical line drawn between the IVC superiorly and gallbladder fossa. Cantile's line separates the functional lobes where as the falciform ligament separates the anatomical lobes
The importance of the functional lobes is they are supplied by the left and right hepatic arteries which is important in terms of resection.
