Quick Answer. Oxygen travels through the human body by being bonded to the iron in a special molecule in blood cells called hemoglobin. This is necessary because, unlike carbon dioxide, oxygen dissolves very poorly in water.
Before blood can begin its journey around the body again, it must travel to the lungs to release carbon dioxide and take in oxygen. The right atrium accepts the oxygen-poor blood and delivers it to the right ventricle, which pushes the blood through an artery to the lungs. The blood then returns in a vein from the lungs to the left atrium, where it waits before passing to the left ventricle and back through the aorta again.
