Although it is about one - third adult size, it is proportionately larger.\nIts lumen is short and funnel-shaped and disproportionately narrower than that of an adult. It lies higher in the neck than the adult larynx. At rest, the upper border of the infant epiglottis is at the level of the second or third cervical vertebra; when the larynx is elevated, it reaches the level of the first cervical vertebra.\nThis high position enables an infant to use its nasal airway to breath while sucking.', 'role': 'assistant'}]
