Blood cells. Coloured scanning electron micrograph (SEM) of a lymphocyte white blood cell (centre) and red blood cells (erythrocytes, circular). Lymphocytes are involved in the immune system's defence mechanisms, lymph system, and 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: x3003, when printed 10 centimetres high.
