In the larynx mucosa there are special cilindric cells that have cili, beating to create a current towards aditis laringis (the upper opening of the larynx). Their purpose is to remove bacteria and other particles. Smoking paralyzes those cili, so bacteria and unwanted particles stagnate in the larynx and the respiratory tractus. Morover, tsmoke contains irritating substances.
