Question

What are the two structures which move during swallowing to make sure bolus enter only the food pipe?

Answer 1

Answer:

First, the tongue pushes the food into the throat. Next, the epiglottis, a small but important flap of tissue, folds over the voice box at the top of the windpipe. This keeps food from going down the wrong way. Finally, the esophagus contracts and moves food toward the stomach.
