Trachea

A large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.

"C" Shaped Cartilages

The rings of hyaline cartilage that support the anterior and lateral sides of the trachea, allowing it to remain open for air passage while being flexible.
