Quizplus · Accepted Answer

When fluid collects in alveoli, it creates a longer distance for gases to diffuse across, which slows down gas exchange. This is because gases diffuse more slowly over longer distances. Option A is incorrect because gases are actually able to dissolve in fluids. Option B is incorrect because the blockage of blood flow through capillaries would affect oxygen delivery to the tissues, not gas exchange in the lungs. Option C is also incorrect because an increase in surface area would actually facilitate gas exchange, not slow it down.
