The aorta carries oxygenated blood to the body. The pulmonary artery carries deoxygenated blood to the lungs and it is the only artery to carry deoxygenated blood. There are two veins associated with the heart. The vena cava, or great vein, carries deoxygenated blood back to the heart from the body.
Generally most veins carry deoxygenated blood. Arteries carry oxygenated blood. The correct way to think about it is that Veins carry blood to the heart, whilst arteries carry blood away from the heart.This means in most cases, the blood carried by veins will be deoxygenated, whilst the blood carried by arteries is oxygenated.he correct way to think about it is that Veins carry blood to the heart, whilst arteries carry blood away from the heart.
