WebbIn much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food called a bolus while in the esophagus and gastrointestinal tract and chyme in the stomach along the gastrointestinal tract. WebbChemical digestion is facilitated by the churning action of the stomach caused by contraction and relaxation of smooth muscles. The partially digested food and gastric juice mixture is called chyme. Gastric emptying occurs within two to six hours after a meal.
