SpletPeristalsis consists of sequential, alternating waves of contraction and relaxation of alimentary wall smooth muscles, which act to propel food along (Figure 23.5). These waves also play a role in mixing food with digestive juices. Peristalsis is so powerful that foods and liquids you swallow enter your stomach even if you are standing on your ... SpletIn clinical practice, there is a “gray area” including unclear physiological conditions and, in these cases, some recently developed parameters, like post-reflux swallow-induced peristaltic wave (PSPW) index and mean nocturnal baseline impedance (MNBI), can be of help in discriminating normal from abnormal findings. 79–83 Further studies ...
