Nettet11. okt. 2024 · Physically, peristaltic waves of amplitude \(\bar{B}\) and wavelength \(\lambda\) along with the magnetic force \(\left( {\bar{B}} \right)\) are responsible to … NettetThe peristaltic, propulsive nature of the slow wave-driven motor activity in the mouse small intestine has been clearly demonstrated: every propagating contraction is associated with outflow of content if flow is not blocked by an area of high pressure (8). Hence this motor pattern is peristaltic in every sense of the word, and not segmental.

A normal esophageal stripping wave transmits a bolus along the esophagus at approximately 2 cm/s. A bolus should clear a normal 25 cm esophagus in less than 15 s. The barium should proceed throughout its entire length in one smooth stripping motion.
