    For all that, how does food travel from the mouth to the stomach?

    Food is pushed through the esophagus and into the stomach by means of a series of contractions called peristalsis. Just before the opening to the stomach is an important ring-shaped muscle called the lower esophageal sphincter (LES). This sphincter opens to let food pass into the stomach and closes to keep it there.

    As it, how quickly does food travel through the body? After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.
