Expert Answer
- The nose has many very important functions in the body.
- It warms, humidifies and purifies the air we breathe.
- The mucous membrane of the nose protects airways against external environment by filtering particles present in the air.
- The small nose hairs on the mucous membrane direct these impurities toward the throat and stomach. Sneezing is another way of getting rid of impurities.
- Proper nasal hygiene helps the mucous membrane protect the body.
- The nose also helps to project our voice and is responsible for the sense of smell.
- It is important to keep our nose clean so that all these functions are smoothly carried out.
