Respiratory System

Structure and Function

What is the larynx?

The larynx is the passage located between the pharynx and trachea that houses the vocal cords. After air leaves the pharynx, it enters the larynx. The larynx is a cartilaginous structure that encloses the glottis. It is formed by three cartilages: the thyroid, cricoid, and the epiglottic. In addition to forming the passageway for air to travel from the pharynx to the rest of the respiratory tract, the larynx is the site of most sound production.
