peristalsis
wavelike constriction passing along a tube, caused by muscular contraction, as found in the esophagus, intestine and so forth

Peristalsis
The wavelike motions of the gastrointestinal tract are aided by the relaxing effect of NO on the smooth muscle in its walls.
Birth
NO also inhibits the contractility of the smooth muscle wall of the uterus.
peristalsis
[Gk. peristellein, to wrap around]
Rhythmic waves of contraction of smooth muscle that push food along the digestive tract.

peristalsis Involuntary contractions of the smooth muscles in the walls of the esophagus, stomach, and intestines that propel food along the digestive tract.
Peristalsis waves of muscle contractions which push food through the digestive system
(peri = around; stalsis = a constriction‚ compression) ...
Peristalsis Movement provided by the smooth muscles to the contents of the digestive tract, ureters, urethra, uterine duct, and vas deferens.
peristomium The segment of the body of an annelid that surrounds the mouth.
The small intestine and remainder of the digestive tract undergoes peristalsis to transport food from the stomach to the rectum and allow food to be mixed with the digestive juices and absorbed.
Peristalsis of the coils of small intestine can be observed in some persons with extremely thin abdominal walls when some degree of constipation exists.
Step 2: Muscles in the esophagus propel the bolus by waves of involuntary muscular contractions (peristalsis) of smooth muscle lining the esophagus. Peristalsis is shown in Figure 4.
2) Food travels down the OESOPHAGUS by peristalsis
3) To the STOMACH

Either they use the general body wall muscles (sponges, Cnidaria, flatworms) or muscles of the blood vessels (annelids) to move fluids around the body. These peristalsis-like movements cause the blood to flow mostly in one direction...
