In which structure are the vocal chords located?

The vocal cords, also known as vocal folds, are located in the larynx, which is a key structure in the respiratory system responsible for producing sound. The larynx is situated at the top of the trachea and is sometimes referred to as the voice box. It contains the vocal cords, which vibrate and create sound when air is expelled from the lungs. This is essential for phonation, allowing humans to speak and produce vocal sounds.

Understanding the other structures can provide context: the trachea is the airway that leads from the larynx to the bronchi, serving primarily as a passage for air but not contributing to sound production. The bronchi branch off of the trachea into the lungs, facilitating air distribution but lacking any sound-producing capabilities. The pharynx, located above the larynx, serves as a pathway for both air and food but does not contain the vocal cords itself.

Thus, the larynx distinguishes itself as the specific structure responsible for housing the vocal cords, making it the correct answer.
