Detailed explanation-1: -Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.
Detailed explanation-2: -Explanation: Smooth muscles are located in the wall of digestive tract. The contraction and relaxation of the muscle creates a movement called “peristalsis". Peristalsis propels food through the digestive tract.
Detailed explanation-3: -In the esophagus, two types of peristalsis occur: First, there is a primary peristaltic wave, which occurs when the bolus enters the esophagus during swallowing. The primary peristaltic wave forces the bolus down the esophagus and into the stomach in a wave lasting about 8–9 seconds.
