The partial pressure of oxygen in the alveoli of the lungs is
1 Equal to that in the blood
2 More than that in the blood
3 Less than that in the blood
4 Less than that of carbon dioxide
Explanation:
The alveolar oxygen partial pressure is lower than the atmospheric \(\mathrm{O}_{2}\) partial pressure for two reasons. Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour (47 \(\mathrm{mmHg}\) ) reduces the oxygen partial pressure to about \(150 \mathrm{mmHg}\).

At which of the following sites is the partial pressure of carbon dioxide \(\left(\mathrm{pCO}_{2}\right)\) highest?
1 Exhaled gas
2 Alveolar gas
3 Arterial blood
4 Venous blood
Explanation:
The partial pressure of carbon dioxide \(\left(\mathrm{pCO}_{2}\right)\) is highest in venous blood i.e. (deoxygenated blood) which is \({\rm{45}}\;{\rm{mmHg}}\).
