  2. Peristalsis - Wikipedia

    en.wikipedia.org/wiki/Peristalsis

    Peristalsis (/ ˌ p ɛr ɪ ˈ s t æ l s ɪ s / PERR-ih-STAL-siss, US also /-ˈ s t ɔː l-/-⁠ STAWL-) [1] is a type of intestinal motility, characterized by radially symmetrical contraction and relaxation of muscles that propagate in a wave down a tube, in an anterograde direction. Peristalsis is progression of coordinated contraction of ...

  3. Basal electrical rhythm - Wikipedia

    en.wikipedia.org/wiki/Basal_electrical_rhythm

    Smooth muscle within the GI tract causes the involuntary peristaltic motion that moves consumed food down the esophagus and towards the rectum. [1] The smooth muscle throughout most of the GI tract is divided into two layers: an outer longitudinal layer and an inner circular layer. [1] Both layers of muscle are located within the muscularis ...

  4. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    The muscle of the inner layer is arranged in circular rings around the tract, whereas the muscle of the outer layer is arranged longitudinally. The stomach has an extra layer, an inner oblique muscular layer. [1] Between the two muscle layers is the myenteric plexus (Auerbach's plexus). This controls peristalsis.

  5. Gastrointestinal physiology - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_physiology

    Peristalsis is one of the patterns that occur during and shortly after a meal. The contractions occur in wave patterns traveling down short lengths of the GI tract from one section to the next. The contractions occur directly behind the bolus of food that is in the system, forcing it toward the anus into the next relaxed section of smooth muscle.

    en.wikipedia.org/wiki/Stomach_rumble

    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. [1]

  8. Gastroileal reflex - Wikipedia

    en.wikipedia.org/wiki/Gastroileal_reflex

    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] This in turn stimulates colonic peristalsis and an urge to ...

  9. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    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 .
