The trachea then divides into two smaller tubes called bronchi. On average the inferior margin of the trachea is the lower border of the manubrium sternii however in full inspiration the elasticity of the trachea. The gaps between the rings of cartilage are filled by the trachealis muscle a bundle of smooth muscle and fibroelastic tissue.

The structure of its wall makes the trachea sufficiently flexible and elastic to permit the transient expansion of the esophagus during swallowing. The proteins elastin collagen and reticular fibers help to maintain the overall elasticity of the tracheal wall while the nerves and blood vessels of the areolar tissue provide for the different layers. Together these hold the lumen of the trachea open but allow flexibility during inspiration and expiration. The adult trachea has a mean diameter of 18 cm and length of 11 cm.
