WebRed blood cells are shaped like a biconcave disc - increases SA:volume ration -> increase surface for oxygen to diffuse in and out of cell. Red blood cells are very small - 7um, compared with 40um average cell -> allows them to fit through capillaries, haemoglobin molecules close to surface -> quick oxygen exchange. Red blood cells are flexible ... WebRed blood cell production is controlled by the hormone erythropoietin, which is released by the kidneys in response to low oxygen levels.
