So in the case of myoglobin, so let's take out a marker. In the case of myoglobin, we begin once again at the lungs, just the same way we begin here at the lungs. So, at the lungs, we have 100 million meter of mercury and that corresponds to about 98% to zero. 98 fractional saturation or 98% of the myoglobin is saturated in the lungs, which is the same value as for the hemoglobin case. But look what happens when we go down to this value which corresponds to the resting tissue. There is only a very, very small drop in a fractional saturation of myoglobin when we go from the lungs to the resting tissue, about 1% difference.
