APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Total hepatic blood flow ranges between 800 and 1200 mL/min, which is equivalent to approximately 100 mL/min per 100 g liver wet weight[4]. Although the liver mass constitutes only 2.5% of the total body weight, the liver receives nearly 25% of the cardiac output.

Detailed explanation-2: -Unlike any other organ in the body, the liver has two blood supplies: 75% of its blood comes in through the portal vein system. This is a network of blood vessels which transport blood through the intestine, stomach, the spleen and the pancreas, draining into the portal vein and then into the liver.

Detailed explanation-3: -The liver is the largest visceral organ in the body, receiving approximately a quarter of the cardiac output. The normal liver has a dual blood supply, deriving 70 to 80% of its blood, rich in nutrients, from the portal vein and the other 20 to 30%, rich in oxygen, from the hepatic artery.

Detailed explanation-4: -The liver holds about 1 pint (13%) of the body’s blood supply at any given moment. The liver has 2 main parts (lobes). Both of these are made up of 8 segments that consist of a thousand small lobes (lobules).
