The graph above demonstrates the relationship between the partial pressure of oxygen and the percent to which blood hemoglobin would be bound to oxygen. 1. At a PO2 of 100 mm Hg, what percentage of hemoglobin sites would be bound to oxygen? 2. At a PO2 of 40 mm Hg, what percentage of hemoglobin sites would be bound to oxygen? 3. Assuming that the alveoli have a PO2 of 100 mm Hg, and blood passes through alveolar capillaries, and then travels to an active muscle tissue that has a PO2 of 20 mm Hg. What percentage of the RBC hemoglobin oxygen content would be released to the muscle?
