Question

Quizplus · Accepted Answer

The cilia are small hair-like structures that line the nasal cavity and help remove pathogens by moving them towards the throat where they can be swallowed or expelled. The pharynx is a muscular tube that connects the nasal and oral cavities to the esophagus and trachea. The nasal septum is a wall that divides the nasal cavity into two halves. The nasal conchae are bony structures that increase the surface area of the nasal cavity. The paranasal sinuses are air-filled cavities in the bones surrounding the nasal cavity. While all of these structures play a role in respiratory function, only the cilia specifically line the nasal cavity and help remove pathogens.
