Which of the following help comprise the defense system of the nose?
I.clearance of foreign matter by ciliary action
II.gross filtration by the large hairs of the nasal vestibule

Question

Quizplus · Accepted Answer

I, II, and III are correct because they describe mechanisms by which the nose filters and removes foreign particles, including the movement of cilia, the trapping of particles by nasal hairs, and the impaction of particles on the mucosa. IV is incorrect because airflow through the concha is not laminar but turbulent, which helps in warming, humidifying, and filtering the air.
