Microvilli are tiny, finger-like projections found on the surface of cells in the respiratory tract, particularly in the lungs. They primarily function to increase the surface area for absorption of nutrients and gases. However, microvilli do not play a direct role in cleaning tar out of the lungs. The clearance of foreign particles like tar is primarily carried out by the mucociliary escalator, a system in which mucus traps particles and cilia move the mucus out of the respiratory tract.

What vitamins help clean out your lungs of tar?

Unfortunately for smokers, there are no vitamins-or anything else for that matter!-capable of removing the tar from inhaled cigarette smoke from the lungs. Once it's in there, it's pretty much there to stay. This is why smoking is so detrimental to health. Each puff of a cigarette adds another layer of carcinogenic tar onto the lungs sensitive tissue, making it harder for the underlying alveoli-sacs to perform their task of absorbing oxygen and excreting carbon dioxide.
