<span>Oxygen carried in a hemoglobin molecule is bound to an iron atom.
</span>The red blood cells contain a pigment called hemoglobin, each molecule of which binds four oxygen molecules.
This protein carries oxygen to the cells and carbon dioxide to the lungs.
It is the iron atom<span> that binds </span>oxygen<span> as the blood travels between the lungs and the tissues.</span>
