The primary function of red blood cells is to transport oxygen from the lungs to the cells of the body. RBCs contain a protein called hemoglobin that actually carries the oxygen. In the capillaries, the oxygen is released to be used by the cells of the body.ach molecule of hemoglobin contains four iron atoms, and each iron atom can bind with one molecule of oxygen (which contains two oxygen atoms, called O 2) for a total of four oxygen molecules (4 * O 2) or eight atoms of oxygen for each molecule of hemoglobin. The iron in hemoglobin gives blood its red color.
