How Air Moves Through the Voice Box, Trachea, and Lungs
From there, it moves down the trachea into the lungs. As air from the lungs passes through the vocal cords, they vibrate.
It connects the pharynx to the trachea and houses the vocal cords, which are two bands of muscular tissue stretched across the opening. The pitch and volume are adjusted by the tension and position of these cords.
How Air Travels from the Voice Box through the Trachea to the Lungs
