Oxygen uptake:The amount of oxygen which can be absorbed and consumed by the working musles from the blood is called oxygen uptake.The oxygen uptake depends on the rate of diffusion which is further determined by the speed of blood flow,temperature and partial pressure of oxygen in the blood and of carbon dioxide in the muscle cell.
