So we go from here to about here. And this wide valley corresponds to about zero point 32. And that means when our tissue is exercising, 32% of that hemoglobin is fully saturated with oxygen. And so now, when we go from the lungs to our exercising tissue, there is a difference of 98% -32%. So 66% and that means 66% of the hemoglobin has unloaded and released that oxygen to the cells of our body that are exercising. And that is a lot of oxygen.
