Expert Solution
Step 1
The exchange of gases between the blood and alveolar air occurs due to the process of diffusion. It is the movement of gases from the higher concentration to the lower concentration.
The concentration of a particular gas in air or within the blood is expressed in terms of pressure exerted by the gas. This is expressed in millimeters of mercury (mmHg).
