The esophagus, sometimes known as the gullet, is an organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. (The pharynx is the part of the neck and throat situated behind the mouth and nasa cavity.

One question I wanted to ask is: What is the purpose of having to eat and swallow your food, in the same orphis that you breathe through? It seems like you would be determined to choke at some time or another.

I researched and found this info. There have a structure in your throat called an epiglottis. The function of the tissue is to cover your trachea as your eating and drinking. Thus preventing food from getting in your trachea and directing it into your esophagus. It works pretty well at preventing choking.

In the next post, I will talk more about esopahgus and epiglottis.
