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.
1. Once the deoxygenated red blood cell (RBC) returns to the heart, it enters either through the superior vana cava or the inferior vena cava. The superior vena cava returns deoxygenated blood from the upper part of the body to the heart.. The RBC returns to the heart through a pulmonary vein, enters the left atrium, passes through the mitral valve, and flows into the left ventricle. 5. The left ventricle pumps the fully oxygenated RBC through the aortic valve, into the aorta, the body's main artery, and out to the body.
