Solution
The correct option is A PO2 in atmospheric air -40mm Hg
Alveoli are the primary sites of exchange of gases. Exchange of gases also occurs between blood and tissues. oxygen and Carbon dioxide are exchanged in these sites by simple diffusion mainly based on pressure/concentration gradient. Pressure contributed by an individual gas in a mixture of gases is called partial pressure and is represented as pO2 for oxygen and pCO2 for carbon dioxide. Out of all the matches given, the correct pair is that the partial pressure of oxygen in atmospheric air is 40 mm Hg.
So, the correct answer is 'pO2 in atmospheric air - 40 mm Hg'.
