Do you mean oxygenated blood? If so, then this would be arteries. This would be because all arteries do so except for the one going to your lungs (pulmonary artery) as it carries deoxygenated blood to the lungs and the pulmonary vein carries oxygenated blood to the heart. Of course, all other veins carry deoxygenated blood around the body. Maybe this is what you meant?-dragon934-
blood
heart
It is a vein.
Arteries are blood vessels that carry oxygenated blood in the lungs to the tissues of the body.Veins are blood vessels that carry deoxygenated blood (venous blood) filled with waste products from the body tissues to the heart and lungs.
Systemic Circulation
They pump blood from the heart into the lungs or all the other tissues of the body.
active transport
The nearest organ to the heart that receives oxygenated blood is the lungs. After blood is oxygenated in the lungs, it returns to the heart via the pulmonary veins. From there, the heart pumps this oxygen-rich blood to the rest of the body, including vital organs and tissues.
Systemic Circulation
Ventricles
The right side of your heart pumps blood to the lungs where oxygen diffuses into the blood, the oxygenated blood is then pumped to the left side of the heart which pumps it to the rest of the body to be delivered to tissues. If the was an infarction (heart attack) That means the blood flow was blocked, the heart tissues almost immediately begins to die and is unable to keep pumping that blood to the lungs in order for the oxygen to be distributed to the rest of the body.
