Question

What would happen if epiglottis is absent in our body

Answer 1

epiglottis is actually a flap like structure between trachea(wind pipe) and food pipe; if there is no epiglottis then there became a single passage for respiration and ingestion of food ,which makes it complex and troubling.

Answer 2

epiglottis is flap like valve structure where it allows the passage of food in to esophagus and air{containing oxygen and other gaseous compounds} into trachea. so, if epiglottis is totally absent in the body then it causes choking which means food can enter into trachea and ultimately human will die.
