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.
At the same time, carbon dioxide moves from the capillaries into the air sacs. The gas has traveled in the bloodstream from the right side of the heart through the pulmonary artery. Oxygen-rich blood from the lungs is carried through a network of capillaries to the pulmonary vein. This vein delivers the oxygen-rich blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding tissues.
