Hurrah, we come to the end of the module! We started by asking how food travels in our body after we swallow it. Gravity definitely helps pull the food down. But, only gravity is not enough.As we learnt, peristalsis makes the food travel through the body. When we are lying flat on a bed, gravity cannot help the food travel along the food pipe. The food still moves due to peristalsis.
