35

36
Function of the pharynx
receive air and food
37

Larynx
41
Where are the vocal cords located and what is their function?
In the larynx; During breathing, they are separated to let air pass. During speech, they close together, and sound is produced as air is expelled from the lungs, causing cords to vibrate against each other.
42
Describe the protective swallowing mechanisms of the pharynx
To protect that only air and not food enter the lungs:
1. The SOFT PALATE, which is the muscular portion of the roof of the mouth, moves up and backward during swallowing to close off the nasoharynx
2. The EPIGLOTTIS, which is a lid-like structure located at the base of the tongue, swings downward and closes off the laryngopharynx so food doesn't enter the trachea/lungs.
