Question

Name the flap that closes the windpipe when you swallow food ?

Answer 1

Epiglottis is equipped with a flap like structure that tends to close the wind pipe while consuming food.

It is an essential step because the food particles can fall into the trap of the wind pipe in the absence of this flap.

Lung alveoli are equipped with blood capillaries for the supply of the oxygenated blood and to help in the respiration process.

It is thus the valve that diverts passage to either the trachea or the esophagus........
