उत्तर
The pharynx is a common passage for both food and air. A cartilaginous flap called the epiglottis closes the opening of the windpipe while eating and thus prevents the entry of food into the windpipe. Sometimes, when one eats hurriedly, talks or laughs while eating, the epiglottis remains open. The food may enter the windpipe and coughing helps to clear it.
