In what group does the trachea belong in?

The trachea belongs to the respiratory system, which is responsible for the exchange of gases in the body. Specifically, it is part of the conducting zone, serving as a passageway for air to travel from the larynx to the bronchi and into the lungs. The trachea is also classified as a tubular structure made of cartilage and smooth muscle, facilitating airflow while maintaining its shape.
