the - is a small flap of tissue that closes the windpipe when you swallow food to keep you from chocking

Answer 1

The statement you provided is not entirely accurate. The small flap of tissue you are referring to is called the epiglottis, not the hyphen or dash. The epiglottis is a small cartilaginous structure located at the base of the tongue, which prevents food and liquids from entering the windpipe (trachea) when swallowing. Its main function is to direct the food and liquids towards the esophagus, which leads to the stomach. Its role is to protect the airway rather than prevent choking.
