    The Trachea is reinforced with cartilage rings to prevent the trachea from collapsing and to keep the airway patent despite the pressure changes that occur during breathing. The advantage of the rings not being complete posteriorly is that the esophagus is allowed to expand anteriorly during swallowing.
