हिन्दीThe partial pressures (in mm Hg) of oxygen (\( O_2 \)) and carbon dioxide (\( CO_2 \)) at alveoli (the site of diffusion) are:
Correct answer · Option 2
\( pO_2 = 104 \) and \( pCO_2 = 40 \)
Explanation
At the alveoli, the partial pressure of \( O_2 \) is 104 mm Hg and \( CO_2 \) is 40 mm Hg.
