Answer 3

air trapping
decreased alveolar perfusion 
increased alv gas pressure
decreased ventilation
decreased vq

Question 4

asthma
__lung volumes = ____
hyperexpansion = ___ retention and ___

by narrowing

Question 12

Chronic bronchitis s.s
thorax \_\_\_\_
pulm htn and cor pulmonae caused by

thorax expands
hypoxemia->polycythemia and cyanosis=pulm htn and cor pulmonale
decreased TV
decreased FEV1
poor exercise tolerance
