You are a Biomedical Engineer interested in developing new drugs to help breathing in premature babies. Surfactant is a complex mixture of phospholipids, ions and proteins. It plays a critical role in increasing oxygen exchange in the alveoli of the lungs, by decreasing the surface tension of water on the alveoli surfaces. If surfactant is at abnormally low levels, then the attraction of water molecules for each other, and hence the surface tension, increases. This increased surface tension causes increased...

The compliance of a flexible structure, such as a balloon, is determined by a curve (volume vs. pressure), rather than being constant. As you inflate a balloon, it gets more and more difficult to achieve a given change in volume. Stated another way, you have to supply a greater change in pressure to achieve a given change in volume when the balloon is at higher volumes vs. when it is at lower volumes. This means that the compliance of the...
