Which part of the respiratory system is responsible for sound production?

The larynx is known as the voice box and plays a crucial role in sound production. It is located at the upper part of the trachea and contains the vocal cords. When air from the lungs passes through the larynx, it causes the vocal cords to vibrate, producing sound. The pitch and volume of the sound can be modified by changing the tension of the vocal cords and the airflow, as well as the shape of the vocal tract. This capability makes the larynx essential for speaking and producing vocal sounds, distinguishing it from other components of the respiratory system. The other structures, such as the lungs, trachea, and bronchi, are primarily involved in the passage and exchange of air rather than in generating sound.
