3. Which structure in the respiratory system is responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream?
- A. Trachea
- B. Bronchi
- C. Alveoli
- D. Bronchioles
Correct answer: C
Rationale: The correct answer is C, Alveoli. Alveoli are tiny air sacs located at the end of the bronchioles in the lungs where the exchange of oxygen and carbon dioxide takes place. Oxygen from the air we breathe diffuses into the bloodstream through the alveoli walls, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. The trachea and bronchi are responsible for carrying air to and from the lungs, while bronchioles are small air passages within the lungs that branch off from the bronchi. However, the actual gas exchange occurs in the alveoli, making them crucial for the respiratory system's function.
