How does peristalsis move your belly?

Peristalsis is a series of wave-like muscle contractions that occur in the digestive tract, including the stomach and intestines. These contractions help propel food and liquids through the digestive system by alternating between contracting and relaxing the circular and longitudinal muscles. As these muscle layers contract, they create a rhythmic motion that moves the contents along, effectively pushing food from the esophagus to the stomach and through the intestines. This process is essential for digestion and nutrient absorption.
