 Peristalsis is the process of wave-like contractions and relaxations of the alimentary tract that propels the food forward through the tract. The wall of oesophagus is muscular. When the slightly digested food enters the food pipe, the walls of the oesophagus starts contraction and expansion movements called peristaltic movements which push the food into the stomach. Digestion does not take place in the oesophagus.
