What is the primary function of the larynx in the respiratory system?

The primary function of the larynx in the respiratory system is to connect the pharynx to the trachea, serving as a vital passageway for airflow between these two structures. The larynx not only provides this connection but also plays a crucial role in protecting the airway during swallowing by preventing food and liquids from entering the trachea. While it facilitates the flow of air to the lungs, it also houses the vocal cords, which are involved in sound production, but this feature is secondary to its function as a conduit in the respiratory tract. Therefore, recognizing the larynx as the bridge between the pharynx and trachea highlights its essential role in respiratory anatomy and function.
