The trachea and major bronchi contain cartilaginous rings. These rings function to prevent collapse of the structure during respiration. During inspiration, a negative pressure force is created within the thoracic cavity by the flattening of the diaphragm and action of the intercostal muscles to raise the ribs. If the trachea were not internally supported, the negative pressure would result in its collapse, preventing air movement and gas exchange.

Tracheomalacia or laryngomalacia is a congenital disorder seen in young children in which the tracheal rings are incomplete or weak and this exact scenario occurs - during inspiration, the trachea collapses and the child cannot breathe and develops respiratory distress.
