The trachea, or windpipe, is the bony tube that connects the nose and mouth to the lungs, and is an important part of the vertebrate respiratory system.

In mammals, the trachea begins at the lower part of the larynx and continues to the lungs. There it branches into the right and left bronchi. Inflammation of the trachea can lead to other conditions, such as tracheitis, which is the inflammation of the linings of the trachea.
