The surface tension in the alveoli of lungs gets considerably increased, because of reduced synthesis of surfactants, which may have occured, as in most cases, due to chronic smoking. This causes permanent expansion of lungs, i.e., once inflated, they can regain their previous original size. Hence, the patient suffers from dyspnoea and other manifestations of emphysema.
