A series of organized, wave-like muscle contractions that occur throughout the digestive tract.
Wavelike muscular contractions of the intestines.
Waves of involuntary contraction in the digestive system.
Rhythmic movement of the gut to push food along the intestinal tract.
Involuntary wavelike contraction occurring along the walls of the hollow tubes of the body, especially the esophagus, stomach, and intestines.
Wave-like motions through the channels of the body, notably the colon.
The rhythmic contractions of muscles of the gastrointestinal tract that aid in propelling food and nutrients through the digestive system.
Wormlike contractions normal to tubular organs, especially of the digestive system.
The movement, like waves ,produced by alternate contraction and relaxation of muscles along an organ such as the intestine or oesophagus, which pushes the contents of the organ along it.
The wavelike movement by which the alimentary tract propels its contents.
The rhythmic contractions of the smooth muscles which surround the gastrointestinal tract.
Rhythmic, wavelike contractions of the smooth muscle of the digestive tract that force food through the tube and wastes toward the anus.
The movement of food through the intestine via smooth-muscle contraction.
Wavelike, rhythmic, muscle contractions that carry food through the digestive tract. Peristalsis occurs from the moment food enters the mouth until waste matter is expelled from the rectum.
A wavelike movement that progresses along some of the hollow tubes of the body. It occurs involuntarily and is characteristic of tubes that possess circular and longitudinal muscles, such as the intestines. It is induced by distension of the walls of the tube. Immediately behind the distension the circular muscle contracts. In front of the distension the circular muscle relaxes and the longitudinal muscle contracts, which pushes the contents of the tube forward.
The worm-like movement by which the stomach and bowels propel their contents. It consists of alternate waves of relaxation and contraction in successive parts of the intestinal tube. Any obstruction to the movement of the contents causes these contractions to become more forcible and is often accompanied by the severe form of pain known as colic.
A progressive wavelike movement that occurs involuntarily in hollow tubes of the body, especially the alimentary canal. It is characteristic of tubes possessing longitudinal and circular layers of smooth muscle fibers.
A succession of waves of involuntary muscular contractions of various hollow tubes of the body, especially of the digestive tract, where it affects the transport of food and waste products.
The rhythmic, wave-like muscular activity of the intestines that helps move along digested food.
The wavelike muscular action that pushes food through the esophagus and the rest of the digestive system.
Peristalsis is a gastrointestinal motility pattern that comprises sequential, rhythmic muscular contractions which expel food along the length of the digestive tube. This motion begins when food boluses are conveyed into the esophagus and continues throughout the entire gastrointestinal tract. Peristalsis is crucial for digestion, as it propels ingested food towards the stomach and small intestine, where nutrient absorption occurs.
Peristalsis is the rhythmic waves of muscular contractions occurring in the intestines, which facilitate the movement of food during the process of digestion.
Peristalsis is the ripple-like motion resulting from the continuous contraction and relaxation of smooth muscles in the walls of the digestive tract and the ureters. This action drives the movement of food and waste throughout the digestive system and channels urine from the kidneys to the bladder.
In the digestive system, food is pushed towards the stomach by peristalsis in the esophagus, even if a person is upside down. Within the stomach, similar muscle actions blend food with stomach acids and then shift the semi-digested mixture into the duodenum, the initial segment of the small intestine. The muscles of the small intestine exhibit a gentle, oscillating motion, facilitating extended nutrient absorption. In the large intestine, peristaltic movements happen roughly every 30 minutes. Yet, two or three times daily, often after eating, a pronounced, consistent wave of peristalsis in the colon pushes its contents to the rectum, potentially triggering the need to pass stool.
A wave-like contraction moves through the alimentary tract inside the body, which consists of both longitudinal and transverse muscle fibers. A segment of the tract contracts and shortens, then relaxes as the next segment contracts. This rhythmic movement pushes the food from one end of the digestive system to the other.
