How does smoking affect your respiratory system? Choose all that apply. Smoking causes the lungs to produce more mucus, which cannot be moved by damaged cilia, leading to a persistent cough as the lungs try to remove particles. Chemicals in cigarette smoke lubricate the lungs, making the respiratory system more efficient. Increased mucus secretions that cannot be removed from the lungs makes smokers more susceptible to respiratory ailments. Chemicals in cigarette smoke destroy or paralyze the cilia lining the bronchi, affecting the ability to remove harmful particles from the lungs.
