In human respiratory system the external nostrils leads to a nasal chamber through the nasal passage. The nasal chamber opens into nasopharynx, which is a portion of pharynx, the common passage for food and air. Nasopharynx opens through glottis of the larynx region into trachea. Larynx helps in sound production. During swallowing glottis can be covered by a flap called epiglottisto prevent the entry of food into the larynx.
