1.  Write a brief description of the changes in the lungs/air passages.

2. What changes in the thoracic musculature would you expect over time in a patient who has

     asthma?

3. Asthmatics have decreased ERV and vital capacity.  Additionally, residual volume and FRC may be increased.  How might asthma impact other respiratory volumes and capacities?
