MICROANATOMY

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: -The portal vein, which arises from umbilical and vitelline veins is the central vessel in which the hepatic cords form around. This helps explain why the portal vein is the primary blood supply for the liver as opposed to the hepatic artery.

Detailed explanation-3: -The central veins, or hepatic veins (HV) collect the blood and lead it to the vena cava inferior.

Detailed explanation-4: -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.
