| However incomplete deglutitive relaxation in LES and primary peristaltic waves were detected in several patients with achalasia. |
| Local stimulation by distension along the body of the esophagus will elicit a peristaltic wave at the stimulus site. |
| Its integrated system design houses the control, temperature and aeration systems, a stirrer motor control unit and up to four peristaltic pumps. |
| The reflex peristaltic contraction sweeps any refluxed gastric fluid back into the stomach. |
| He also suggested an expiratory wave of peristaltic smooth muscle contraction starting from the periphery to aid in exhalation. |
| The normal esophagus responds immediately with a reflexive peristaltic contraction, a phenomenon called secondary peristalsis. |
