Question

Quizplus · Accepted Answer

Peristaltic contractions occur throughout the digestive tract, including the stomach, esophagus, small intestine, and large intestine, to move food along. They are not primarily for mixing food with digestive juices (that's more the role of segmentation movements in the small intestine) nor are they of similar strength throughout the digestive tract, as the force can vary depending on the location and the needs of the digestive process.
