Question

describe the way peristalsis moves food through your digestive system. it uses gravity to push the food through. its muscles are always open allowing food to fall through. its muscles constrict and relax in waves, allowing the food to move through. food is pushed through by eating more food.

Explanation:

Peristalsis is the rhythmic contraction and relaxation of muscles in the digestive - tract walls. This wave - like motion propels food along the digestive system. Gravity is not the main factor in peristalsis, and muscles are not always open, nor is food pushed by eating more food.

Answer:

It's muscles constrict and relax in waves, allowing the food to move through.
