The part of your question actually was the answer. 

The pseudostratified ciliated columnar epithelium of the trachea produces mucus inorder to capture particles of dust, bacteria, and debris; swings the mucus to the throat where it can be swallowed and arranges the airway that is being open by C-shaped rings (cartilagenous).
