  • Question
  • Which part of the respiratory system does emphysema damage?


  • Options
  • A. Nose
  • B. Lungs
  • C. Trachea
  • D. Mouth

  • Correct Answer
  • Lungs 

    Explanation

    Emphysema is a condition that involves damage to the walls of the air sacs (alveoli) of the lung i.e, primarily causes shortness of breath due to over-inflation of the alveoli.

     

    First, emphysema causes holes to gradually form inside the lungs' air sacs, thereby weakening their internal structure and inhibiting the exchange of oxygen and carbon dioxide.
