How exactly does food move through the digestive tract?

A doctor has provided 1 answer

From top to bottom: Fodd is chewed (hopefully) in the mouth, and swallowed by coordinated muscular contractions in the mouth and throat, entering the esophagus, where the same muscular contractions push it down to the stomach. Churning action and enzymes, acid break the food chunks into smaller particles that are pushed, again by muscles of the GI tract, through the small intestine, eventually to reach the colon.
