The larynx and the windpipe, while both vital parts of the respiratory system, are distinct structures with different roles. The windpipe is actually another name for the trachea, which is a tube that carries air. The larynx, on the other hand, is also known as the voice box. It's a more complex structure that contains the vocal cords.
| Feature | Larynx (Voice Box) | Windpipe (Trachea) |
|---|---|---|
| Primary Function | Produces sound, protects the lower airway, and helps regulate airflow. | Transports air to and from the lungs. |
| Location | Situated at the top of the trachea. It’s between the pharynx (throat) and the trachea. | Extends from the larynx down to the bronchi (which are the main airways to the lungs). |
| Structure | Contains the vocal cords, which vibrate to produce sound. Has cartilage that makes it possible to swallow and to protect the airway. | A long, U-shaped tube made of rings of cartilage. It's a simple airway. |
| Nickname | Voice box | Windpipe |
How they work together
The larynx and trachea work closely together in the breathing process. When you inhale, air travels from your mouth or nose, through your larynx, and then into your trachea before reaching your lungs. The larynx not only allows for breathing, but also closes when you are swallowing to prevent food or liquid from entering the windpipe and lungs.
Summary
- Larynx: The voice box; located at the top of the windpipe.
- Windpipe: Also called the trachea; the main airway to the lungs, below the larynx.
