A typical RBC is about 6-8 micrometers in diameter, about the same as the width of a spider web strand. The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin accepting CO2 and releasing O2. Lymphocytes are cells that circulate in your blood that are part of the immune system. Functions of red blood cells The main function of erythrocytes is the transfer of oxygen, which is carried out thanks to hemoglobin a special protein in their composition.
