Description
Red and white blood cells. Coloured scanning electron micrograph (SEM) showing two types of cells found in human blood. Red blood cells (or erythrocytes, red) and a white blood cell (or leucocyte, white) can be seen. Red blood cells are biconcave disc-shaped cells which transport oxygen around the body. Their red colour comes from the oxygen-carrying protein haemoglobin. The white blood cell is roughly spherical with cell projections on its surface. White blood cells are part of the body's immune system, which protects against infections. Magnification: x 3000 when printed at 10cm wide.
