peristalsis
Peristalsis is the name of the digestive tract muscles pushing the food along... Is this what you were referring to?
Peristalsis is the wavelike motion of muscles that pushes food downward through the digestive tract. It helps propel food and liquids from the esophagus to the stomach and through the intestines for digestion and absorption.
Peristalsis is the contraction of the digestive muscles. Peristalsis is the contractions that occur in the smooth muscles of the body.
by peristalsis which is the rhythmic, involuntary contraction of the smooth muscles in the walls of digestive organs.
Peristalsis is the contraction of smooth muscles that cause food to move throughout the digestive tract.
The wavelike contractions of the smooth muscle in the gastrointestinal system are called peristalsis. The purpose of peristalsis is to push boluses of food along the gastrointestinal tract. This is achieved by the waves of contractions in the smooth muscle followed by relaxation of the muscles, pushing the bolus (ball of food) a bit further along the digestive tract with each contraction. These contractions move food or chyme through the esophagus, and intestines. The same contractions also move urine down the ureter to the bladder.
Contraction of smooth muscles to carry contents through the digestive tract. Examples are in the esophagus and small intestine.
Anerobic contraction of muscles.
Peristalsis
The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.
Peristalsis is a symmetrical contraction of muscles which propagates in a wave down the muscular tube, more specifically the esophagus. In humans, peristalsis is found in the contraction of smooth muscles to propel contents through the digestive tract.In much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food (called a bolus while in the esophagus and gastrointestinal tract and chyme in the stomach) along the gastrointestinal tract. Peristaltic movement is initiated by circular smooth muscles contracting behind the chewed material to prevent it from moving back into the mouth, followed by a contraction of longitudinal smooth muscles which pushes the digested food forward.
The general opposite of contraction is expansion, or possibly inflation. For muscles, the opposite of contraction is relaxation.
