So we have the right pulmonary vein and the left pulmonary vein that both carry the oxygenated blood. So once again, we see that veins always carry blood to the heart but they can carry both oxygenated as well as deoxygenated blood. In this case, they bring the oxygen blood into number six, which is basically our left atrium. So once again, the atrium of the heart always receives that blood. So in number six, it then moves into the left atrium of the heart. Now, from six, once again, we have this valve system that moves our oxygenated blood into our left ventricle.
