How does the epiglottis behave .What would happen it you talk while eating?
The short answer is : the epiglottis is a movable flap of tissue
attached behind/under the tongue which blocks the entrance to the
trachea. There is also a sound box called Larynx which sends out
vibrations when we talk and due to this vibrations the flap opens
and sometimes food goes inside and we start coughing. If you talk
while eating, and you happen to be a toddler, your Mum will tell
you off. If you talk while eating, and you are older than that,
people may think you are a bit of a pig.....
