Vomiting.
Peristalsis.
peristalsis.... the reason why food travels through the esophagus into the stomach is that it is moved along by contractions of smooth muscle surrounding the esophagus. This is known as peristalsis
peristalsis
The esophagus (also spelled Oesophagus) is the tube that connects the mouth and the stomach. It works through continuous wavelike muscle contractions known as peristalsis, along with downward gravity, to move food and liquids from the mouth and throat into the stomach.
Stimulating the gag reflex in the throat is usually enough to do it if you are determined (see bulimia). Otherwise, vomit-inducing substances such as ipecac oil will suffice. You worded your question poorly. Reverse peristalsis is far more commonly known as vomiting.
Peristalsis
nope. gullet
The food is sort of squeezed down by the esophagus due to the contraction of smooth muscles present on the inner side of the esophagus and this contraction is actually a movement known as peristalsis. It is just like squeezing something inside a tube or a pipe.
Esophagus develops from foregut and by week 10 is lined by ciliated epithelial cells. -Beginning at 4 months, the ciliated epithelium starts to be replaced by squamous epithelium. At either end of the esophagus the ciliated epithelium gives rise to esophageal glands. -The upper esophagus is derived from branchial arches 4, 5, and 6, but the derivation of the lower esophagus is not known. -The development of various elements of esophageal wall requires coordination of a variety of genes and mediators. -Esophageal peristalsis appears in the first trimester, and gastroesophageal reflux can be documented in the second trimester.
