Peristaltic
Definition:
(a.) Applied to the peculiar wormlike wave motion of the intestines and other similar structures, produced by the successive contraction of the muscular fibers of their walls, forcing their contents onwards; as, peristaltic movement.
Example Sentences:
(1) The effects of drugs applied in the bathing medium on the peristaltic responses were examined.
(2) One is the ureteral peristaltic contraction which plays a principal role in urinary bolus transport at low flows; the other is ureteral wall tonus, which plays an important role in the transport of columns of urine by the ureter, which does not coapt its walls, at the higher flow rates.
(3) We conclude that retained gastric peristaltic function is not a prerequisite for a good clinical outcome for swallowing and that despite vagotomy, the stomach continues to produce enough acid to maintain an acidic pH.
(4) The changes in the motor pattern resemble those of the intrinsically mediated 'peristaltic reflex', studied in animals, and suggest that in man the response to balloon distension may also be mediated through an intrinsic mechanism.
