The cilia are hair-like structures that line the respiratory tract and move in coordinated waves to sweep pathogens and debris out of the lungs, helping to protect against respiratory infections. Mucous membranes and the vestibule are also parts of the respiratory system, but they do not play as significant a role in removing pathogens from the lungs. Internal nares are the openings between the nasal cavity and the pharynx, which help to facilitate breathing but are not directly involved in the body's structural defenses against respiratory infections.
