43 & 44:
Both are respiratory diseases, but they affect different parts of respiratory system. Asthma infects the airways and emphysema attacks the lung tissue.
A spirogram of a person with restrictive lung disease would show reduced VC, TLC, FRC, and RV.

10. What effect does opening the valve have on the left lung? Why does this happen?

It deflates. Intrapleural pressure allows the lung to recoil and the surface tension of the aveloar fluid.

Activity 1:
1.   MRV = TV X BPM – MRV= 7500 ml/min
2.   The ERV does not include the tidal volume. ERV is the amount of air that can be expelled after a tidal exhalation. Therefore the tidal volume is not included int the ERV.
Activity 2:
Exercise 2: Chart 1   FEV1 as % Of VC
Radius (mm)   FEV1 (ml)   Vital Capacity (ml)   FEV1 (%)
5.00   3541   4791   0.7390
4.50   2303   3143   0.7327
4.00   1422   1962   0.7248
3.50   822   1150   0.7148
3.00   436   621   0.7021

1.   The FEV1 percentage will decrease as the airway radius is decreased. The FEV1 percentage is the amount of air that can be expelled from the lungs in one second during expiration. As the airway becomes smaller, the resistance to the airflow will increase and the FEV1 percentage will decrease.
Activity 3:
1.   The FEV1 percentage decreases as the airway radius decreases.
2.   The airflow increased when the surfactant was applied because the resistance to the lung inflation has been reduced.
3.   Since surfactant actually decreases the resistance of lung inflation, it is actually beneficial. However, premature infants do not have surfactant so they do not get the decreased resistance for lung inflation, hence trouble in breathing.

One or more volumes together equals a capacity.
