cilia protect you lungs by stopping and bacteria and dust from reaching them. if the cilia is damaged then dust and bacteria will be able to get down you throat and cause a lot of damage. hope this helped :)
Smoking affects your circulation. The cilia that move cells through blood in your body are damaged. Blood vessels are damaged. Your heart beats faster and your blood pressure goes up.

Smoking.
bronchial tubes
Occasional smoking temporarily disrupts the sweeping action of tiny hairs called cilia. Long-term exposure to cigarette smoke causes the cilia.
The cilia, which help to remove mucus and debris from the lungs, are impaired, making it harder for the body to clear out harmful substances. Excessive mucus production can lead to congestion, coughing, and difficulty breathing. Over time, this can contribute to lung diseases like chronic bronchitis and emphysema.
Cigarette smoking induces cancer, by damaging the cell's ability to absorb oxygen! The cells are actually poisoned by the thousands of toxic chemicals in tobacco products. The cilia of the respiratory tract are damaged and destroyed. In such a case they do not help the tract remove tobacco smoke and other toxins.
The tar from the cigarettes sticks to the cilia, the tiny hair-like structures that line the airways in the lungs. The cilia typically acts as little brooms that sweep out harmful dirt - but when cigarette is smoked, the cilia can't work properly because the tar sticks to the cilia and is therefore covered

you die of ventilation problems... :(
Cigarette smoke irritates cells in the bronchi and this irritation triggers special cells to produce a layer of mucus designed to trap the foreign particles irritating the cells. This layer of mucus is then suppose to be swept away by the Cilia, though the tar found in cigarette smoke slows the action of the cilia. This tar accumulates in the mucus layer, because the cilia are not able to respond due to the presence of this tar. In conclusion, the mucus layer will gradually grow over time because the cilia will not be able to sweep away the accumulated foreign particles.
