Final answer:

Cigarette smoke impairs cilia function, leading to respiratory issues like pneumonia.

Cigarette smoke affects cilia in the respiratory system by paralyzing them, which impairs their ability to sweep mucus out of the airways and inhibits production of mucus. This leads to a dysfunction in the clearing of respiratory passages and increases the risk of respiratory conditions like pneumonia.
