Your lungs are the reasons you body has Oxygen. In your lungs, we do produce mucus, which we cough up because of the cilia in our lungs. Smoking causes this cilia to not move the mucus out of your lungs which in turn causes problems.

yes lungs can get blocked by mucus if tha is what you mean :)
Well one of the answers i know of is that your mucus coats the inside of your stomach preventing your stomach acids from eating through your body.
The hairs and the mucus inside the nose trap and collect dust, bugs and other debris and prevent it from entering the lungs.
Water vapor in the lungs does not condense because the air we breathe in is already close to 100% humidity, so there is no significant temperature difference to cause condensation. The lungs are also lined with a thin layer of mucus that helps keep the surfaces moist and prevents water vapor from condensing inside the lungs.
The scientific name for mucus is "sputum" when referring to mucus from the respiratory tract, and "phlegm" when referring to mucus from the throat or lungs.
It can cause a buildup of phlegm and mucus in the airways, but not in the lungs.
