A vein is an elastic blood vessel that transports blood. It carries blood with less oxygen content back, from the body to the heart. But the pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart.
The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. But the pulmonary artery carries blood which is rich in carbon dioxide from the right ventricle of the heart to the lungs for oxygenation.
