Which answer is most correct concerning capillary microcirculation and oxygen diffusion?
A) the combination of small surface area, fast rate of blood flow and thick layer of endothelial cells makes this an ideal place for gas exchange
B) the combination of large surface area, slow rate of blood flow and thin layer of endothelial cells makes this an ideal place for gas exchange
C) the combination of small surface area, slow rate of blood flow and thick layer of endothelial cells makes this an ideal place for gas exchange
D) the combination of large surface area, fast rate of blood flow and thick layer of endothelial cells makes this an ideal place for gas exchange

Question

Quizplus · Accepted Answer

Capillary microcirculation is characterized by a large surface area for gas exchange, slow rate of blood flow to ensure sufficient time for diffusion, and a thin layer of endothelial cells to facilitate the diffusion of oxygen and other gases. This is why option B, which describes these factors accurately, is the most correct answer.
