aExtension of the head and neck, as when maintaining an airway in an anesthetized patient, may stretch the trachea and increase its length by 25%. In the adult, the carina may descend by as much as 3 cm on deep inspiration. At the carina, the right bronchus leaves the trachea at an angle of 25° from the vertical and the left bronchus leaves the trachea at an angle of 45° from the vertical. In children younger than 3 years, both bronchi arise from the trachea at equal angles.
bAs children grow, the diameter in millimeters corresponds approximately to their age in years.
