Question

7. How is swallowed food prevented from going to the lungs?​

Answer 1

Answer:

When you breathe, air enters your mouth and moves into the pharynx. The air then goes down into your main airway (trachea) and into your lungs. A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow.

Answer 2

Explanation:

• By the presence of a flap like structure called epiglottis which prevents the entry of food in wind pipe.
• When we swallow food, it goes into the food pipe. To prevent food from entering the lungs, a flap called the epiglottis closes the lung pipe and thus, food doesn't enter your lungs.
