Q. Regarding the elastic properties of the lung: (Solved)
1. the lung volume at any given pressure during inflation is larger than during deflation
2. the area under the pressure-volume curve is known as the compliance
3. surface tension is the force acting across an imaginary line in the surface of the liquid
4. pressure generated in an alveolus equals 4T/R
5. surfactant, produced by Type I alveolar cells, reduces surface tension in alveoli
- c. surface tension is the force acting across an imaginary line in the surface of the liquid
