Which statement is true about parts of the respiratory system? a. the nose warms, moistens, and filters air before it reaches the lungs. b. the nose is designed primarily for expiration. c. the pharynx is separate from the throat. d. the trachea is separate from the windpipe.

Well, It cannot be A. as the trachea is the windpipe, so its not separated.

I think your answer is definitely C. because that says exactly what the nose does so it makes it true and the other ones are false.

Hope I helped :)

I Think It's B Because The Pharynx Is In The Throat
