The function of the nasal cavity, what are the functions of the nasal cavity?
1, respiratory function: the beginning of the airway, the passage of breathing, no one has a problem with this, right?
2, olfactory function: the olfactory nerve is our first pair of cranial nerves, oh, ENT also always manage a first, oh, just kidding. Taste good or not all depends on the nose, although often can smell some abnormal taste, but it can still be very important ah, otherwise you do not know the flower tea thick.
3, resonance function: simply put is the pronunciation function, of course, the resonance cavity is not simply limited to the nasal cavity, there are oropharynx and other key parts of the pronunciation, but if rhinitis attack, pronunciation is definitely affected, which is why you have a cold, others can hear the reason. Is there a feeling of instant awakening.
4, protection function: This function is also the most important (personal opinion, because it is closely related to my career, there are singing that the resonance function is the most important ah, well I was wrong, huh) protection function includes filtering, heating, humidification three major functions. Once the rhinitis attack loss of protective function after a series of airway problems, many times rhinitis attack when the source of airway disease.
In short: the three main functions of the nasal cavity is, breathing, smell, resonance, protection.
In common parlance, they are: breathing, smelling, humming, and watching the door.
