Where does the exchange of oxygen and carbon dioxide take place within the lungs?
1. Bronchioles
2. Larynx
3. Correct:
Alveoli
Correct answer
4. Windpipe
Feedback
Rationale: The alveoli or air sacs are where the exchange of oxygen from the lungs and
carbon dioxide from the capillaries of the circulatory system takes place. High partial
pressure of oxygen in the alveoli diffuses into the low partial pressure of oxygen in the
capillaries and high partial pressure of carbon dioxide in the capillaries diffuses to the
low partial pressure of carbon dioxide in the alveoli.
