Peristalsis is the rhythmic contraction of smooth muscles to propel contents through the digestive tract.
In much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food (called bolus while in the esophagus and chyme below the stomach) along the gastrointestinal tract. Peristaltic movement is initiated by circular smooth muscles contracting behind the chewed material to prevent backflow, followed by a contraction of longitudinal smooth muscles which pushes the digested food forward.

Peristalsis. Movement of food in the opposite direction is known as anti-peristalsis,which results in vomiting.

Peristalsis is the rhythmic contraction of the smooth muscle in the digestive tract and it's what moves the food through the digestive tract.

it's part of the digestion since the body has already absorbed all of the nutrients and is breaking it down into waste that we can get rid of.
