Peristalsis;
the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wave-like movements which push the contents of the canal forward.
Reverse peristalsis;
Retroperistalsis is the reverse of the involuntary smooth muscle contractions of peristalsis. It usually occurs as a precursor to vomiting. Local irritation of the stomach, such as bacteria or food poisoning, activates the emetic center of the brain which in turn signals an imminent vomiting reflex.

Answer:
The swallowed food travels to the stomach because of a wave-like motion in the walls of the oesophagus called peristalsis.
