The epiglottis is pushed downward and the larynx is lifted up to meet it when we swallow. true false

The correct answer is true.

Explanation:

Swallowing of food is the process of passing the food from the mouth to the stomach through the way of the throat (pharynx) and esophagus. This process takes place in three stages:  oral, pharyngeal, and esophageal stages  

During the pharyngeal stage, epiglottis which is a leaf-shaped flap of cartilage located at top of the larynx (a muscular organ forming voice box) perform functions in response to the swallowed food as the larynx lift up or rises inside the neck to close the epiglottis while the epiglottis moves downward to cover it, providing more airway protection.

Thus, true is the correct answer.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
