Which of these is demonstrated by the oxygen-hemoglobin dissociation curve?
A. The greater the PO2 of the blood, the greater the dissociation of O2 from hemoglobin. B. At normal resting systemic arterial PO2 , hemoglobin is almost 100% saturated with oxygen. C. At normal resting systemic venous PO2 , only about 75% of the hemoglobin is in the form of deoxyhemoglobin. D.

As PO2 increases, the saturation of hemoglobin with oxygen increases linearly.
