WebAbstract. In normal subjects, exercise widens the alveolar-arterial PO2 difference (P [A-a]O2) despite a more uniform topographic distribution of ventilation-perfusion (VA/Q) ratios. While part of the increase in P (A-a)O2 (especially during heavy exercise) is due to diffusion limitation, a considerable amount is caused by an increase in VA/Q ... WebUnder normal conditions, the region expected to have the lowest PCO2 is the _____ A. pulmonary capillaries. B. systemic capillaries. C. atmosphere. D. lungs. 2. If the atmospheric Pressure(CO2) exceeded the alveolar Pressure(CO2) the pulmonary capillary Pressure(CO2) would _____ A. increase well above normal range. impurity\u0027s 6j
