Different types of muscle contractions
The primary mixing or churning organ in the human body is the stomach. It is responsible for breaking down food into smaller particles and mixing it with gastric juices to form a semi-solid mixture called chyme. The muscle contractions in the stomach wall help to churn and mix the food, aiding in digestion.

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.
By rhythmic movements called peristalsis. They are wavelike contractions of smooth muscle that propel food through the GI tract.
