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.
The venae cavae empties the deoxygenated blood into the right atrium of the heart. The venae cavae has two divisions. The superior vena cava resembles a drain that leads down into the heart. Its job is to return deoxygenated blood to the heart from the head and arms. The inferior vena cava has a bigger area to drain, and its job is to return deoxygenated blood to the heart from all body regions below the diaphragm.
