Which of the following are effects of surface tension forces in the air-filled lung?
1) It increases the elastic recoil of the lung (promoting collapse).
2) It makes the lung harder to inflate than if it were filled with fluid.
3) It decreases the lung's elasticity as volume increases.

Question

1) Surface tension contributes to the lung's elastic recoil, making it tend to collapse. 2) The presence of air-water interfaces within the lung increases surface tension, making the lung harder to inflate compared to if it were filled with fluid, which would have minimal surface tension effects.
