But in every mammal, we've just got the one tube, and all that separates the digesting part from the breathing part is a little flap called the epiglottis.
Pharyngeal phase, in which the movements of the soft palate, larynx and epiglottis separate the air passage from the food passage so that food and drink are not aspirated into the nose or trachea.
It must have been really frustrating because you want to connect with people who know everything that goes into it, not just, like, where your epiglottis is or something like that.
The epiglottis lies over the entrance to the larynx. In the act of swallowing, when food and liquid move through the throat, the epiglottis closes off the larynx, so that these things cannot enter.
