Blood cells. Light micrograph of healthy human blood cells. Two white blood cells (blue,centre left and lower right) are seen amongst the red blood cells (grey). Red blood cells transport oxygen around the body. Oxygen binds to haemoglobin in the cells and is released where it is needed. White blood cells form part of the body's immune system. Some engulf foreign organisms while others release chemicals to destroy them. Magnification: x320 at 6x4.5cm size | |
