Final answer:
The larynx, also known as the voice box, is the organ responsible for voice production, located between the pharynx and trachea. It houses the vocal cords necessary for producing sound as air passes through them.
Step-by-step explanation:
The correct definition for the term larynx is C) organ of voice production. The larynx is an organ of the respiratory system located between the pharynx and the trachea, often referred to as the voice box. It contains the vocal cords, which are essential for the production of vocal sounds. Air from the lungs passes across the thin tissues of the larynx, causing them to vibrate and produce sound.
The pharynx is a tube-like structure that connects the mouth and nasal cavity with the larynx and esophagus, allowing both air and food to pass. When one swallow, the epiglottis, a flap of elastic cartilage, closes over the opening to the larynx to prevent food from entering the larynx and trachea.
