B. Transpulmonary pressure:
Defines the pressure across the lung. It is equal to the alveolar pressure minus the intrapleural pressure.
C. Transthoracic pressure:
Defines the pressure across the chest wall, or the total pressure required to expand or contract the lungs and chest wall together. 

2. A.10 cm H2O, B. 2.5 cm H2O 

3. The base of the lung; when you are upright, this is the dependent portion of the lung. 

4. A. Compliance, B. Resistance, C. Active exhalation, D. Ventilatory pattern 

5. Loss of elastic fibers. Lung tissue may be more compliant, but hyperinflation can result in decreased compliance.
