Question

Functional residual capacity and total lung capacity increase in __________.

a) obstructive pulmonary disease
b) restrictive pulmonary disease
c) asthma
d) emphysema
e) Answers a, b, and d are correct.
f) Answers a, c, and d are correct.

Answer 1

Functional residual capacity (FRC) and total lung capacity (TLC) increase in obstructive pulmonary diseases such as emphysema, asthma, and obstructive pulmonary disease (COPD).

Step-by-step explanation:

In obstructive pulmonary diseases such as emphysema, asthma, and obstructive pulmonary disease (COPD), functional residual capacity (FRC) and total lung capacity (TLC) increase. In emphysema, the destruction of alveoli walls reduces the surface area for gas exchange, leading to increased compliance and air trapping in the lungs. Asthma and COPD also result in obstructed airways and increased lung volumes.
