(A) The trachea is lined with ciliated pseudostratified columnar epithelium. The cilia (tracheal hair) beat in a rhythmic,coordinated manner to move mucus,along with trapped dust particles and pathogens,upwards towards the pharynx. This process,known as the mucociliary escalator,helps in clearing the respiratory tract and preventing infections.
