mucus
Mucus in the nose helps trap particles entering the respiratory system. The hairs/cilia of the respiratory system also filter incoming air.

Nose hairs.
It helps us to breathe more comfortable.
Cilia are the tiny hairs that sweep dust and dirt out of the respiratory system.
The system that exchanges oxygen and carbon dioxide between blood and air is the respiratory system. This process occurs in the lungs, where oxygen is taken in from the air we breathe and carbon dioxide is released from the blood into the air we exhale.
The respiratory system helps to exchange oxygen and carbon dioxide between the air and blood for cellular respiration. It also helps regulate pH balance in the body by controlling the levels of carbon dioxide in the blood. Additionally, it helps filter out harmful particles and pathogens from the air we breathe.
the cilia filtrate the air going into the system
Cilia in the nose are tiny hair-like structures that help filter and clean the air we breathe by trapping dust, pollen, and other particles. The cilia move in a coordinated manner to sweep these particles out of the respiratory system, preventing them from entering the lungs and causing irritation or infection.
Nose hairs help to filter out dust, pollen, and other particles from the air that we breathe in. They trap these particles, preventing them from entering the respiratory system and causing irritation or infection. This helps to keep the respiratory system healthy and functioning properly.
The respiratory system supplies the body with O2 (respiration). This system also disposes of CO2 (ventilation). The respiratory system houses the olfactory receptors. Gas exchange between blood and air in the alveoli(external respiration)Gas exchange between the blood and cellular tissue (internal respiration).
