To show students that gravity alone is not the only force that helps move food through the body, the teacher does a headstand and eats a cookie.
Which of the following is MOST responsible for moving the food to the teacher's
stomach while upside down?

If you ate a cookie while you were upside down, your body would try it's best to bring the food to the stomach. There are other forces other than gravity that will help the cookie get to the stomach.

Hope this helps!
