Arteries carry blood away from the heart and veins carry blood towards the heart. The vena cava brings deoxygenated blood from the body towards the heart. However, the coronary artery carries oxygenated blood to the myogenic heart muscle.
oxygenated blood is blood that carries oxygen. It is carried in arteries from the lungs to the left side of the heart and around the body. There is only one vein that carries oxygenated blood and that's the pulmonary vein. deoxygenated blood is blood that carries Carbon dioxide.
