Aus Dornheim Anatomy
The second layer is the tunica fibromusculocartilaginea andt contains the hyaline cartilage brace. This causes the change in the diameter of the bronchi, which serves to control the distribution of air. Even in case of negative intrathoracic pressure, the tunica fibromusculocartilaginae keeps the lumen open.
