Correct Answer

Explanation

Gaseous exchange is a process of diffusion, where gases move from an area of high concentration to an area of low concentration. In this process, gases diffuse across the respiratory membrane, which separates the air in the alveoli from the blood in the capillaries. During inhalation, oxygen moves from high partial pressure in the alveoli to low partial pressure in the blood, while carbon dioxide moves from high partial pressure in the blood to low partial pressure in the alveoli during exhalation. This passive process of diffusion is crucial for the exchange of gases in the lungs.
