Question

lungs take in and release air
which statement about lungs shows how structure is related to function?
lungs are large and spongy
lungs are small and spongy
lungs are small and hollow
lungs are large and rigid

Explanation:

The lungs' function is to take in and release air (gas exchange). A large surface area (implied by "large") and a spongy texture (which allows for more space and flexibility) are beneficial for maximizing gas exchange. Small size would limit the amount of air that can be processed. A rigid structure would not allow for the expansion and contraction needed during breathing. A hollow structure alone (without being large and spongy) is not as effective for efficient gas exchange as the lungs need.

Answer:

Lungs are large and spongy
