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.
Deoxygenated blood is carried by veins from the body to the right side of the heart. The right ventricle pumps the deoxygenated blood to the lungs via the pulmonary arteries. â¦ Oxygen diffuses into the blood in the lungs, and carbon dioxide diffuses out of the blood into the lungs.t then travels through the mitral valve to the left ventricle, from where it is pumped through the aortic semilunar valve to the aorta. The aorta forks, and the blood is divided between major arteries which supply the upper and lower body.
