Pharynx and Larynx

Pharynx: The nasal cavity leads into an organ called the pharynx. From the pharynx, air passes into a chamber called the larynx. The larynx produces sound and is also called the voice box. The opening of pharynx, into the larynx, is guarded by a valve called the epiglottis. This valve closes this opening when we take in the food; it keeps it open during breathing.
