which of the following is not a function of body cavities? options: cushion viscera during walking, jumping, and running; permit expansion of certain viscera; prevent friction; none of the listed responses are correct; protect delicate organs from accidental shocks; permit free movement of viscera; i dont know yet

Explanation:

Body cavities cushion organs (like during movement), allow expansion (e.g., lungs), prevent friction (via serous fluid), protect from shocks, and allow free movement. So all listed functions are correct, making "None of the listed responses are correct" the answer.

Answer:

None of the listed responses are correct.
