- Yoga helps your body reabsorb and expel gas by stimulating peristalsis, the muscle contractions that eliminate waste.
- The pumps operate on the theory of peristalsis as is commonly seen in the human digestive system.
- Waves of muscle contractions called peristalsis force food down through the esophagus to the stomach.
- Capsule endoscopy uses a wireless video capsule that is swallowed by the patient and propelled by peristalsis.
- The initial colonization of the walls of the ureter is in areas of turbulent flow which leads to paralysis of peristalsis.

Derivatives

peristaltic

adjective pɛrɪˈstaltɪk

Physiology

These signals pace the peristaltic contractions, determining their frequency, velocity, and direction of migration.
Example sentencesExamples
- The radiologist commented on poor peristaltic activity.
- Local stimulation by distension along the body of the esophagus will elicit a peristaltic wave at the stimulus site.
- The normal esophagus responds immediately with a reflexive peristaltic contraction, a phenomenon called secondary peristalsis.
- He also suggested an expiratory wave of peristaltic smooth muscle contraction starting from the periphery to aid in exhalation.

peristaltically

adverb

Physiology
