Why does COPD cause prolonged expiration?

The length of the airways in moderate COPD might be longer than in mild COPD, and the radiuses of the airways in moderate COPD might be smaller than in mild COPD, because hyperinflation of the lungs increases airway length and decreases airway diameter due to the loss of elastic recoil and compression caused by the …

Does COPD affect inhalation or exhalation?
