What are two structures that help trap dust and smoke before it enters the respiratory system?

Two structures that help trap dust and smoke before they enter the respiratory system are the nasal hairs and the mucous membranes. Nasal hairs, or vibrissae, filter larger particles from the air, while the mucous membranes lining the nasal passages produce mucus that traps smaller particles and pathogens. Together, these structures play a crucial role in protecting the lungs from irritants and contaminants.
