Where does gas exchange occur?.
The alveoli.
The bronchioles.
The bronchus.
The lungs.
The Correct Answer is A
Choice B rationale:
The bronchioles are part of the airway that leads to the alveoli, but gas exchange does not occur here.
Choice C rationale:
The bronchus is a larger airway that leads to the bronchioles and then to the alveoli, but gas exchange does not occur here.
Choice D rationale:
While the lungs contain the alveoli where gas exchange occurs, saying that gas exchange occurs in the lungs is not as precise as saying it occurs in the alveoli.
