Question 5 of 5
Where does the primary exchange of gases occur in the respiratory system?
Correct Answer: C
Rationale: The primary exchange of gases occurs in the alveoli, which are small, thin-walled sacs located at the ends of the bronchioles in the lungs. It is in Karls alveoli that oxygen (O₂) from inhaled air diffuses into the bloodstream, and carbon dioxide (CO₂) from the bloodstream diffuses into the alveoli to be exhaled.
