Peristalsis
The wavelike contractions of the smooth muscle in the gastrointestinal system are called peristalsis. The purpose of peristalsis is to push boluses of food along the gastrointestinal tract. This is achieved by the waves of contractions in the smooth muscle followed by relaxation of the muscles, pushing the bolus (ball of food) a bit further along the digestive tract with each contraction. These contractions move food or chyme through the esophagus, and intestines. The same contractions also move urine down the ureter to the bladder.
Muscular contractions.
Peristalsis is the term for the rhythmic contractions of the esophagus. These wavelike contractions move food toward the stomach.

peristalsis
By rhythmic movements called peristalsis. They are wavelike contractions of smooth muscle that propel food through the GI tract.
Peristalsis is the wavelike motion of muscles that pushes food downward through the digestive tract. It helps propel food and liquids from the esophagus to the stomach and through the intestines for digestion and absorption.
Involuntary contractions of the muscles, classically the long muscles associated with standing (the anti-gravity muscles).
The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.
