: The [[trachea]] contains [[Specialised Cell|specialsed cell]]s which release [[mucus]] in order to trap [[micro-organism]]s and dust to prevent them entering the [[lung]]s.
: The inner lining of the [[trachea]] is covered in [[Ciliated Epithelial Cell|ciliated epithelial cells]] to sweep the [[mucus]] up away from the [[lung]]s.
===About the Trachea===
: The [[trachea]] splits into two smaller pipes called [[Bronchus|bronchi]].
