What effect does a reduced ventilation perfusion ratio have on end-capillary PO₂ and PCO₂? A) end capillary PO₂ will decrease and end capillary PCO₂ will increase B) end capillary PO₂ will increase and end capillary PCO₂ will decrease C) end capillary PO₂ and PCO₂ will both decrease D) end capillary PO₂ will decrease while end capillary PCO₂ will remain constant

A reduced ventilation perfusion ratio indicates that there is less ventilation relative to perfusion. This leads to less oxygen being delivered to the blood (decreasing PO2) and less carbon dioxide being removed from the blood (increasing PCO2).
