2. Introduction Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.

3. Esophageal Peristalsis Peristaltic waves in esophagus start from the upper position of the tube and pass into the complete length and impel the food into the stomach. This could be termed as Esophageal Peristalsis.

4. Intestinal Peristalsis The stimulation of smooth muscle tissues for the existence of food particles in the small intestine is responsible for contractions that travel from the restorative point in both directions is termed as Intestinal Peristalsis.

5. Segmentation is another kind of involuntary muscle movement that occurs in your digestive system. But unlike peristalsis, which occurs throughout your GI tract, segmentation occurs mainly in your intestines. Segmentation activates circular muscles in your intestines that contract to move food back and forth, a bit like the churning of a washing machine. This churning gives food in the intestines a chance to mix with gastric juices and helps break it down into smaller pieces for digestion. Segmentation slows the progress of food through your GI tract somewhat, but peristalsis continues to move it gradually along . What is the difference between peristalsis and segmentation?
