Question
Hb in the blood leaving the lungs is about 99% saturated with oxygen.
Hb in the blood leaving actively respiring muscle tissue is about 10% saturated
with oxygen.
Based on the above curves, each mole of oxygen binding sites in Hb is delivering
about 0.49 moles of oxygen from the lungs to the muscles.
Hb in the blood leaving actively respiring muscle tissue is about 50% saturated
with oxygen.
Based on the above curves, each mole of oxygen binding sites in Hb is delivering
about 0.89 moles of oxygen from the lungs to the muscles.
