Increasing alveolar ventilation increases the blood pH because
++
++
++
A. it activates neural mechanisms that remove acid from the blood.
++
++
B. it makes hemoglobin a stronger acid.
++
++
C. it increases the Po2 of the blood.
++
++
D. it decreases the PCO2 in the alveoli.
++
++
E. the increased muscle work of increased breathing generates more CO2.

In uncompensated metabolic alkalosis
++
++
++
A. the plasma pH, the plasma HCO3– concentration, and the arterial PCO2 are all low.
++
++
B. the plasma pH is high and the plasma HCO3– concentration and arterial PCO2 are low.
++
++
C. the plasma pH and the plasma HCO3– concentration are low and the arterial PCO2 is normal.
++
++
D. the plasma pH and the plasma HCO3– concentration are high and the arterial PCO2 is normal.
++
++
E. the plasma pH is low, the plasma HCO3– concentration is high, and the arterial PCO2 is normal.
