I'm confused because I thought arteries were AWAY from the heart and the veins are towards the heart, meaning they supply the heart while the arteries take things away from the heart and to the rest of the body. But reading over the notes in class and the powerpoints online..... it clearly states that the Coronary arteries supply oxygenated blood to the heart and the veins take away deoxygenated blood.
  Blood passes from the right ventricle to the lungs via the pulmonary artery (the only artery in the body that contains deoxygenated blood veins In the circulatory system â¦ , a vein is a blood vessel that carries blood back toward the heart (as opposed to artery, a blood vessel carrying blood away from the heart).he majority of veins in the body carry low-oxygen blood from the tissues back to the heart; the exceptions being the pulmonary and umbilical veins which both carry oxygenated blood Specifically, the superior and inferior vena cava carry deoxygenated blood back to the heart.
