Rhythmic contraction of smooth muscle that forces food through the digestive tract

wavelike muscular contractions that help to move food down the digestive system

movement of the esophagus, induced by swallowing, in which waves of alternate circular contraction and relaxation propel the contents (bollus) onward. The act of peristalsis utilizes up to 50 pairs of muscles, and takes from 17-23 seconds to complete

Muscular movements of the intestinal tract that function to propel contents longitudinally through the tract.

The rippling motion of muscles in the digestive tract. In the stomach, this motion mixes food with gastric juices, turning it into a thin liquid.

Rhythmic, wave-like contractions of smooth or involuntary muscle fibers that propel food through the digestive tract.

A wave-like movement that travels along some of the hollow tubes in the body, such as the digestive tract. It is brought about by the coordinated contraction and relaxation of muscles in the walls of the hollow tubes, and serves to move material through the tubes in a specific direction. It is an involuntary (subconscious) process.

successive muscular contractions along the wall of a hollow, muscular structure

The rolling motion of smooth muscle that moves food along the alimentary canal. Includes the passage from the esophagus to the stomach, the churning action of the stomach, and the passage through the small intestine.

the major means of propulsion in moving food along the digestive tract. Consists of a series of alternating contractions and relaxations of smooth muscle that lines the walls of the digestive organs and that forces food to move forward.

a rhythmic series of muscular contractions that propels the bolus along.

stalsis = a contraction, from stellein = to constrict; progressive contractile wave along body tubes (Culpeper, 1655); adj. peristaltic.

(pair´ i stall´ sis) [Gr. peri: around + stellein: place] • Wavelike muscular contractions proceeding along a tubular organ, propelling the contents along the tube.

The waves of contractions and relaxation of the intestinal muscles needed to move the contents.

rhythmic, wavelike contraction of smooth muscle in intestines or other tubular structures; circular contraction and relaxation of the tube propels its contents

A wave-like contraction in an organ, such as the intestines, which propels the contents.

the process of wave-like muscle contractions of the alimentary tract that moves food along

Greek peri = around, and stellein - to constrict; hence, a circular constriction passing as a wave along a tube; adjective - peristaltic.

Contraction of the muscles in the digestive system in a wavelike fashion, such that foodstuff is moved down from the mouth and through the stomach and intestinal tract for elimination through the rectum. Motility disorders typically cause abnormalities with paristalsis.

Progressive contraction and relaxation of the intestines.

Progressive waves of contraction and relaxation of a tubular muscular system, esp. the gastrointestinal tract, through which the contents are forced through the system.

The means by which food is propelled through the esophagus in a series of muscular contractions. This same process is used by the intestines to propel digested food and waste.

A series of normal coordinated muscle contractions that occur automatically, for example to move food through the digestive tract.

A wave-like squeezing motion in a tube. Food moves down the esophagus by peristalsis. A mouse moves through a boa constrictor by peristalsis.

waves of involuntary contractions passing along the walls of the intestines, moving digested food along and forcing evacuation.

contractions of muscles in the gastrointestinal tract that mix and move the contents

Contraction of the esophagus, stomach, small intestine and colon. Peristalsis boost food or liquid through the GI tract in a coordinated fashion.

The movement of the intestine or other tubular structure, characterised by waves of alternate circular contraction and relaxation of the tube by which the contents are propelled onward

synchronized, sequential contractions of smooth muscle in the gastrointestinal tract that mixes and pushes food toward the colon and rectum.

rhythmic muscle movements that force food in the esophagus from the throat into the stomach. Peristalsis is involuntary - you cannot control it. It is also what allows you to eat and drink while upside-down.

wave-like movements of food forward through the digestive tract.

wavelike contractions that move food through the digestive tract.

involuntary wave-like movement in hollow tubes within the body, especially the digestive system

A progressive, wavelike movement which occurs involuntarily in hollow tubes of the body, especially noted in the intestines, but also in present in the ureters.

the process of contraction and expansion by which food is moved through your intestines and into your bowel.

wavelike movement of muscles in the GI tract that moves food and liquid through the GI tract.

Movement characterized by alternate circular contraction and relaxation of the intestine or other tubular structure which propels the contents onward.

Involuntary contractions of the smooth muscles in the walls of the esophagus, stomach, and intestines that propel food along the digestive tract. Waves of muscle contraction in the esophagus that propel food from the oral cavity to the stomach. PICTURE

wave-like muscular contractions in the walls of tubular organs, e.g. the alimentary canal. Peristalsis serves to push material contained within the organ along its length.

The wave like movement of the intestine that moves the contents through from the stomach to the rectum.

wavelike contractions of the smooth muscles of the digestive tract; also, the wavelike contraction of the colon muscles that expel waste mater.

Normal rhythmic movements of the stomach and intestine.

wavelike contractions along the esophagus, stomach, or intestine, that function to keep the contents moving in the right direction at a healthy pace

to surround, involve the rhythmic, wavelike motion of the walls of the alimentary canal and certain other hollow organs

Synchronized or coordinated contraction of the muscles that propel food content through the gastrointestinal (GI) tract to facilitate normal digestion and the absorption of nutrients. Peristalsis is dependent upon the coordination between the muscles, nerves, and hormones in the digestive tract.

a series of involuntary muscular contractions that form a wave-like motion to propel food through the esophagus to the stomach. This same process is used by the intestines to propel digested food and waste.

Wave of contractions of the intestinal tract.

Contractions of the muscular layers of the GI tract that propel food forward.

The rhythmic, wave-like contraction of muscles that propels food along the digestive tract.

Peristalsis is the rhythmic waves by which organs provided with both longitudinal and circular muscle fibers propel their contents.

The rippling motion of muscles in the intestine or other tubular structure characterized by the alternate contraction and relaxation of the muscles that propel the contents onward.

wave-like muscular contractions in the smooth wall of the gut which move food through the alimentary canal Humans as organisms

Waves of contraction that progress for short distances down the intestine propelling the contents onward. Compare segmentation.

The movement or wave of contractions and relaxation of the tube by which the contents are propelled onward. A worm like progression of alternate contraction and relaxation of the muscle fibers of the ureter, which propels urine down the ureter into the bladder.

The waves of contraction and relaxation of the smooth muscle of the digestive tract.

Wavelike movement of intestinal muscles that propels food along the digestive tract (see Digestive Health).

Peristalsis is the rhythmic contraction of smooth muscles to propel contents through the digestive tract.
