Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, where it binds to hemoglobin. One molecule of hemoglobin can bind four molecules of oxygen (O2). The partial … See more Red blood cells are filled with hemoglobin. Hemoglobin is a globular protein comprised of four polypeptide chains with an iron-binding group called heme on each chain.
