Quizplus · Accepted Answer

Smoking damages the cilia in the respiratory passages, which are hair-like projections that help to remove bacteria and other foreign particles from the lungs. When the cilia are damaged, the lungs are less able to clear away bacteria, making smokers more susceptible to respiratory infections. Smoking also irritates and inflames the respiratory tract, making the environment more hospitable to bacteria and viruses.
