Question

Swallowing of food hurriedly or laughing while swallowing causes voilent coughing. What is the reason

Answer 1

 Sometimes when we eat in a hurry,talk or laugh while eating,we may get hiccups or a choking sensation.This happens when food particles enter the windpipe.The windpipe carries air from the nostrils to the lungs.It runs adjacent to the foodpipe.But inside the throat,air and food share a common passage.During the act of swallowing a flap like valve closes the passage of thye windpipe and guides the food into the foodpipe.If,by chance ,food particles enter the windpipe,we feel choked and get hiccups
