Right left lobeCholecystocaval or cholecysto-vena caval line divides liver into right and left physiological lobes.Physiological right and left lobes are equally divided by an imaginary line cholecysto-vena caval line running from fossa for gall bladder to the groove for IVC. The physiological right and left lobes have separate biliary drainage and vascular supply, i.e. they are superior respectively by right and left branches of poal vein and hepatic aery and bile is conveyed by the corresponding hepatic ducts bile ducts .
