The vein carries your normal blood throughout the human body.
oxygenated blood
The renal vein carries deoxygenated blood from the kidneys to the heart.
Oxygenated blood is carried by the pulmonary vein. This vein transports blood from the lungs to the heart.
The renal artery carries blood to the kidney, and the renal vein carries blood that has been purified by the kidney.
There are two veins that carry oxygen they are the Pulmonary vein and the Umbilical vein:-)
In a medical setting, the process of blood going into an IV is typically carried out by inserting a needle into a vein, then connecting a tube to the needle that allows blood to flow from the vein into a bag or container. The blood is then administered to the patient through the IV tubing.
It's the only vein that carries oxygenated blood. It brings this oxygenated blood back to the heart (into the left atrium) where it can then be pumped around the body.
The clean blood in the renal vein is carried back to the heart to be circulated throughout the body. This blood is important for delivering oxygen and nutrients to tissues and organs, as well as removing waste products.
The pulmonary artery carries blood from the heart to the lungs
Nutrients are the rich material carried by the hepatic portal vein to the liver and then to the heart. The liver receives about seventy-five percent of its blood through the hepatic portal vein.
blood in pulmonary vein is oxygenated and is carried from lungs to heart(and yet is named pulmonary VEIN).Vena cava is the broadest vein,it is associated to the heart. It receives deoxygenated blood from the veins coming to heart from different body parts and gives it to heart for pumping. I hope it clears your doubt.
Galen was the first surgeon to learn the arteries, veins carry blood, not air
