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.
The circulatory system is big and complex. The basics are that generally arteries convey oxygenated blood, while veins carry deoxygenated blood. The left side of the pig conve â¦ ys oxygenated blood and the right conveys deoxygenated. The only exception to the artery vein rule is in the pulmonary artery and vein.he pulmonary artery then carries deoxygenated blood away from the left ventricle to the lungs. To start the right atrium conveys blood from the superior vena cava to the right ventricle.
