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. And it's the left ventricle that creates the hydrostatic pressure, the hydrostatic force that essentially propels and moves that oxygen blood filled with nutrients into the largest artery of the body known as our aorter. And from the aorter, we basically diverge our aorter into the ascending and descending aorter. So this is number nine.
