Question

Quizplus · Accepted Answer

The respiratory defense system includes structures such as the nasal hairs and mucus, which can trap and filter large airborne particles before they can enter the respiratory system. Choanae, the soft palate, nasal sinuses, and nasopharynx also play a role in filtering and humidifying air, but they are not specifically designed to filter large particles.
