Cilia..they are finger-like things lining the pleural cavity of your lungs. And when you smoke, or get second-hand smoke or other pollutants in your lungs, you cough because the cilia are trying to push all the crap out. Smoking damages them..and can take years to grow back and function properly.
The tiny hairs in the lungs that sweep out dirt and mucus are called cilia. These hair-like structures help to keep the airways clear by moving debris upwards towards the throat where it can be swallowed or expelled.
well basically the ciliated cells line all the air passages in your lungs.they have tiny hairs which filter the air as it blows through the hairs also sweep mucus (snot) with trapped dust and bacteria up to the back of the throat where it is swallowed.

Cilia are tiny hairs that line the respiratory tract and help trap dust and foreign particles to prevent them from entering the lungs. These hair-like structures wave in a coordinated manner to move mucus and trapped particles out of the respiratory system.
hair lining the lungs and aiways are called cillia
