-the effect of emphysema on O₂ and CO₂ exchange within the lungs
A)This change would increase the rate of gas transfer.
B)This change would decrease the rate of gas transfer.
C)This change would have no effect on the rate of gas transfer.

Question

Quizplus · Accepted Answer

Emphysema, which is characterized by destruction of the alveolar walls and loss of elastic recoil, leads to a decrease in the surface area available for gas exchange and a decrease in the efficiency of ventilation-perfusion matching. As a result, the rate of gas transfer is decreased.
