Physiology of trachea

Essential in the physiology of the trachea and indeed the rest of the respiratory tree to keep the cavities open. In the trachea this is done by the tracheal rings which extend 5/6th of the way around the perimeter of the trachea. Equally important are cilia which beat to discourage accumulation of debris and also cough reflex which assists in expectorating debris and foreign bodies.
