Blood cells. Coloured scanning electron micrograph of a lymphocyte white blood cell (left) and a red blood cell (erythrocyte, right). Lymphocytes are involved in the immune system's defence mechanisms, lymph system, and involved in antibody production. The main function of red blood cells is to distribute oxygen to body tissues and to carry waste carbon dioxide back to the lungs. Magnification x9000 when printed 10 centimetres wide.
