Quizplus · Accepted Answer

All of these events occur in smokers. Cigarette smoking damages the cilia in the trachea and replaces ciliated epithelium with squamous epithelium. This impairs the ability of the trachea to move mucus and debris out of the airway, causing it to accumulate. This accumulated mucus can lead to respiratory infections. Smoking also irritates and inflames the trachea, which stimulates the cough reflex.
