Subsequently, one may also ask, what are the 4 stages of swallowing?

• Esophageal Phase.

Subsequently, question is, what is involved in swallowing? Swallowing, sometimes called deglutition in scientific contexts, is the process in the human or animal body that allows for a substance to pass from the mouth, to the pharynx, and into the esophagus, while shutting the epiglottis.

Just so, how does the swallowing process work?
