\mathrm{PC}{\mathrm{O}_2}

III. high

\mathrm{PC}{\mathrm{O}_2}

IV. low

\mathrm{P}{\mathrm{O}_2}

V. low

{H^ + }

VI. High

{H^ + }

Choose the correct option

View answer and explanation

Correct option: D

I, II and V

Option D (I, II and V) is correct because alveoli have high

\mathrm{P}{\mathrm{O}_2}

, low

\mathrm{PC}{\mathrm{O}_2}

, and low

{H^ + }

concentration due to gas exchange.
