Practice Question
Which of the following respiratory structures is affected by a disease that disrupts gas exchange, such as emphysema?
Answer Choices:
Correct Answer:
Alveoli
Rationale:
◈ Alveoli are the tiny air sacs in the lungs where gas exchange of oxygen and carbon dioxide takes place.
◈ In diseases like emphysema, the alveolar walls are damaged or destroyed, reducing the surface area available for effective gas exchange.
◈ This leads to decreased oxygen absorption and impaired carbon dioxide removal, which causes shortness of breath and decreased respiratory function.
◈ The bronchi and trachea are part of the airways but not the direct site of gas exchange.
