A simplified image showing peristalsis. 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.
The peristalsis and segmentation, detailed below and pendular movement are famous examples of distinct patterns of GI contraction. [5] Occurring between meals, the migrating motor complex is a series of peristaltic wave cycles in distinct phases starting with relaxation, followed by an increasing level of activity to a peak level of peristaltic ...
Peristalsis is the rhythmic contraction of muscles that begins in the esophagus and continues along the wall of the stomach and the rest of the gastrointestinal tract. This initially results in the production of chyme which when fully broken down in the small intestine is absorbed as chyle into the lymphatic system .
A stomach rumble, also known as a bowel sound, peristaltic sound, abdominal sound, bubble gut or borborygmus (pronounced / ˌ b ɔːr b ə ˈ r ɪ ɡ m ə s /; plural borborygmi), is a rumbling, growling or gurgling noise produced by movement of the contents of the gastrointestinal tract as they are propelled through the small intestine by a series of muscle contractions called peristalsis.

The physical sensation of hunger is related to the contractions of the muscles of the empty stomach. Peristalsis takes place even when the stomach is empty, and these contractions—sometimes called hunger pangs once they become severe—are believed to be triggered by high concentrations of the ghrelin hormone.

The gastroileal reflex is stimulated by the presence of food in the stomach and gastric peristalsis. Initiation of the reflex causes peristalsis in the ileum and the opening of the ileocecal valve (which allows the emptying of the ileal contents into the large intestine, or colon). [ 1 ]
Swallowing, also called deglutition or inglutition [1] in scientific contexts, is the process in the body of a human that allows for a substance to pass from the mouth, to the pharynx, and into the esophagus, while shutting the epiglottis.
