The nose serves as the first line of defense by filtering and trapping airborne pathogens, dust, and allergens through its mucous membranes and fine hairs called cilia. These structures help prevent harmful particles from entering the respiratory system. Additionally, the nasal passages contain immune cells that can initiate an immune response against pathogens. This filtering and immune activity play a crucial role in protecting the body from infections and maintaining overall respiratory health.
