Question

Which statement is true about parts of the respiratory system? A. The trachea is separate from the windpipe. B. The nose is designed primarily for expiration. C. The nose warms, moistens, and filters air before it reaches the lungs. D. The pharynx is separate from the throat.

Answer 1

can some one help me out

Answer 2

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 :)
