Question

The partial pressures (in mmHg ) of oxygen O 2 and carbon dioxide CO 2 at alveoli (the site of diffusion) are:, p O 2 = 104 and p C O 2 = 40, p O 2 = 40 and p C O 2 = 45, p O 2 = 95 and p C O 2 = 40, p O 2 = 159 and p C O 2 = 0 . 3

Partial pressures (in mmHg ) of O 2 and CO 2 at different sites of the body and in the atmosphere: Respiratory Gases Atmospheric pressure Alveoli Oxygenated Blood Deoxygenated Blood Tissues O 2 159 104 95 40 40 CO 2 0 . 3 40 40 45 45

Respiratory Gases	Atmospheric pressure	Alveoli	Oxygenated Blood	Deoxygenated Blood	Tissues
$O_{2}$	$159$	$104$	$95$	$40$	$40$
${CO}_{2}$	$0.3$	$40$	$40$	$45$	$45$
