The Hepatic Portal Vein
from hepatic portal vein and hepatic artery
The single vessel that drains blood from the digestive tract organs to the liver is the hepatic portal vein. Blood flow to the liver is unique, in that it receives both oxygenated and partially deoxygenated blood.
i think it is because of rich supply of deoxygenated blood of the venus return form the portal veins and oxygenated blood from the portal arterioles .
The blood vessel that carries out this task is called the Hepatic Portal Vein
there are two types of vessels in our body to circulate blood . they are1 arteries - collect the deoxygenated, impure blood from all parts o of the body to theheart (except pulmonary artery which carry oxygenated pure bblood from the lungs to the heart)2veins-- carry pure and oxygenated blood from the heart to various parts of the body(except pulmonary vein which carry the impure deoxygenated impure blood from the heart to the lungs)hencehepatic veins are the veins which carries the impure ,deoxygenated blood, collecting from the liver by the hepatic venules to the heart to purify the blood with oxygen.
hepatic vein
Simple answer: Veins Complex answer: a series of blood vessels (excluding arteries) carries deoxygenated blood from the body to the heart. Where the blood is then passed through an oxygenating process with the lungs. Another answer: pressure caused by the beating of the 4 chamber heart.
Deoxygenated blood is typically found in the venous system and contains carbon dioxide and waste products that are filtered by the liver, kidneys, or lungs.
The hepatic vein drains de-oxygenated blood from the liver into the inferior vena cava.
The blood that passes through the liver is deoxygenated blood (there is no oyygen in the blood when it passes through the liver as it has been used up by other cells, tissues and organs), therefore the liver appears blue.
It receives blood from two (2) sourcesThe Hepatic Artery- it delivers oxygenated blood from the general circulationThe Hepatic Portal Vein-it carries deoxygenated blood containing nutrients from the small intestine.
