These passageways are called: Nasal turbinates or conchae 16 of 20 The structure that protects the tracheal opening from food entrance is called the The epiglottis 17 of 20 The widened section of the trachea that houses the opening is called the The larynx 18 of 20 The nostril is called the The external naris 19 of 20 The internal architecture of the nasal cavity is formed by which bone The ethmoid bone 20 of 20
