A) Constriction of the bronchial tree, excessive mucus, and nonproductive cough

Question

Quizplus · Accepted Answer

Emphysema is characterized by overinflation of the alveoli, causing them to become less effective in gas exchange. This results from destruction of the walls of the alveoli, typically due to smoking, which leads to loss of elasticity and destruction of the air sacs. Constriction of the bronchial tree, excessive mucus, and coughing are more typical of asthma or chronic bronchitis. Calcification of the alveoli is not a feature of emphysema or any other respiratory disease.
