Discussion:
Respiration
1. What is forced vital capacity and how does it relate to lung volumes
2. What does the table indicate about vital capacity and subjects age, sex, height, smoker, asthmatic or athlete, do the findings support previous studies.
3. What is peak expiratory flow and what is the effects of sitting, standing and lying on this measurement. (what effect do any of those positions have on the trachea)
