Cilia are tiny hair like fibers that are located in our broncial tubes. They keep stuff from going into your lungs that don't belong there more or less like a filter. By the way, smoking kills the cilia and allows harmful particles to enter the lungs causing what is referred to as smokers cough. If a young person quits smoking the cilia may grow again but for older smokers the chances are slim that the cilia will ever come back.
