The nose filters out particles and impurities from the air we breathe, including dust, pollen, and microorganisms. It does this primarily through the nasal mucosa and tiny hair-like structures called cilia that trap and expel these unwanted particles. Additionally, the nasal passages humidify and warm the air, preparing it for the lungs. This filtering process helps protect the respiratory system and maintain overall respiratory health.
