Blood cells, TEM
Blood cells, coloured transmission electron micrograph (TEM). Seen here are red blood cells (erythrocytes, red) and white blood cells (yellow, with purple nuclei). The main function of red blood cells is to distribute oxygen to body tissues, and to carry waste carbon dioxide back to the lungs. White blood cells are part of the immune system; they destroy and remove old or aberrant cells and cellular debris, as well as attack infectious agents (pathogens) and foreign substances.
