Regarding the oxygen-hemoglobin dissociation curve which of the following is true
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 systematic venous PO2, only about 75% of the hemoglobin is in the form of deoxyhemoglobin d. more addtional oxygen binds to hemoglobin when going from a PO2 of 60 to 100 mmhg, than is added when going from a PO2 of 40 to 60 mmhg e. as PO2 increases, the saturation of hemoglobin with oxygen increases linearly.
