Question

What will be pO2 and PCO2 of oxygenated blood as compared to tissues respectively? O High, high O Low, high O Low, low O High, low​

Answer 1

Answer:

(ii) The pO

2

(partial pressure of oxygen) will be higher in the atmospheric air compared to that in the alveolar air. The pCO

2

(partial pressure of carbon dioxide) will be lesser in the atmospheric air compared to that in the alveolar air. In atmospheric air, pO

2

is about 159 mm Hg. In alveolar air, it is about 104 mm Hg. In atmospheric air, pCO

2

is about 0.3 mm Hg. In alveolar air, it is about 40 mm Hg.
