why does nose have hair? do you know why?

Everything has its reason.like you said ,the exists of the hair inside the nose is for keep dust away from your nostri.If it's useless,it will disappear early or late.now it's playing its role quietly, more or less,we should thank it,because of its protecting us.

Hi, jcyap888, Look at my insert photo. Nasal hair, or Nose hair is the hair in the nose. Adult humans have hairs in the anterior nasal passage. These hairs act as a fibrous filter for inhaled particles. Diffusion of ultra fine particles to the nasal hair occurs mostly for particles

Yes..you are correct...I learned that from that movie Osmosis Jones..ha ha

This is called nasal hair. These hairs act as a fibrous filter for inhaled particles. Diffusion of ultra fine particles to the nasal hair occurs mostly for particles

There is hair in our nose because it is there to protect our body from harmful particles. Our nose hair would block those harmful particles like dust and other gases like carbon dioxide, so that there would be less harmful particles that would enter our lungs.

the hair filter the air, you allready said so

Hello jc!(",) Nose hairs are the first of several mechanisms for keeping foreign material out of our lungs. They will filter out only fairly coarse dust, like sawdust, but that's of some importance because later mechanisms would have more trouble getting rid of the coarse particles once they were stopped. Nose hair is also our first line of defense to get rid of foreign particles from entering our lungs through the nose. Great day!(",)

well base from what i learn back in school days..nose hair are there to protect the nose itself from the dust and harmful thing that we can smell..so it wont irritate the nose which can lead to severe case.
