Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What important things happen at the pharyngeal phase?
A
The swallow sequence is rapid, for breathing to resume
B
Food and drink enter the oesophagus
C
The bolus is mixed with saliva
D
The airway is protected so food and drink does not enter the lungs
Explanation: 

Detailed explanation-1: -The soft palate rises, the hyoid bone and larynx move upward and forward, the vocal folds move to the midline, the epiglottis folds backward to protect the airway, and the tongue pushes backward and downward into the pharynx to propel the bolus downward.

Detailed explanation-2: -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.

Detailed explanation-3: -As food enters the throat, a small flap called the epiglottis covers the windpipe to direct food toward the stomach and prevent you from inhaling it.
