[[Media:Example.ogg]]'''Smoker's cough''' is a kind of [[cough]] seen especially in smokers. Any irritant present in the [[respiratory system]] may trigger cough, however, smoker's cough develops as a consequence of [[phlegm]] buildup in the [[trachea]]. Many long-term smokers end up beginning their day with bouts of severe coughing. |

==Cause== |

In the trachea, the walls are lined with [[cilia]], small hairs that protrude from the tracheal [[epithelium]]. They move in a synchronous wavelike motion, thereby moving foreign bodies trapped in phlegm upwards towards the [[oropharynx]], so they may be swallowed. Cigarette smoke destroys or paralyzes these cilia, so the only way that phlegm can be removed is via coughing. |
