hey can someone help me with this questions from novmeber 2011 variant 1
Which does not increase the efficiency of gaseous exchange in the alveoli?
A The blood capillaries and alveoli have a large total surface area.
B The blood flow is slowed as it passes through the pulmonary capillaries.
C The walls of the alveoli and capillaries are moist.
D The walls of the alveoli and capillaries are very thin.
why is the answer C ?? i always studies that moist surfaces help rapid diffusion of the gases?
