The erythrocytes, or red blood cells as they are more commonly known as, transport oxygen to the body's cells and extract the carbon dioxide and send it to the lungs to be excreted.
To carry oxygen
Red blood cells perform the blood's primary function of transporting materials (gases, nutrition, wastes) to and from the various tissues of the body and this is why there are more red blood cells than white blood cells. White blood cells provide the blood's secondary functions of immunity and clotting and therefore do not need to be as many.
