6. Which respiratory structure is responsible for the production of mucus to trap particles and for the movement of cilia to sweep mucus and trapped particles out of the respiratory tract?

• A. Trachea
• B. Larynx
• C. Bronchi
• D. Respiratory epithelium

Correct answer: D

Rationale: The correct answer is D: Respiratory epithelium. The respiratory epithelium is a specialized tissue lining the respiratory tract that produces mucus to trap particles and contains cilia that beat in a coordinated manner to move the mucus and trapped particles out of the respiratory tract. The trachea, larynx, and bronchi are all structures within the respiratory system, but they do not directly produce mucus or have cilia for sweeping particles. Therefore, the respiratory epithelium is the specific structure responsible for these functions.
