The conducting portion of the respiratory tract, which includes the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles, is lined with pseudostratified ciliated columnar epithelium. This type of epithelium contains both ciliated and goblet cells which help move mucus and debris out of the respiratory tract.
