THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The inferior vena cava is a large main vein that carries blood through the liver and back to the heart. Blood leaves your liver through a central vein in each lobule, and then through a hepatic vein, one of several short veins originating within the lobes of the liver as small branches.

Detailed explanation-2: -Central veins are located at the centers of liver lobules. The vicinity of a central vein (unlike a portal area) normally includes little or no connective tissue. Sinusoids open freely into the central vein. The central vein in turn provides a “drain” from the lobule into the hepatic vein, which leads to the vena cava.

Detailed explanation-3: -The liver receives a blood supply from two sources. The first is the hepatic artery which delivers oxygenated blood from the general circulation. The second is the hepatic portal vein delivering deoxygenated blood from the small intestine containing nutrients.
