ANATOMY

Detailed explanation-1: -In the nostrils, air gets warmed and moistened. Tiny hairs in the nose called cilia (SIL-ee-uh) filter out dust and other particles.

Detailed explanation-2: -Tiny hairs called cilia (pronounced: SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

Detailed explanation-3: -Your trachea is part of your tracheobronchial tree. The tracheobronchial tree is where air travels to your lungs and exchanges gases (carbon dioxide and oxygen). Your tracheobronchial tree includes: Trachea.

Detailed explanation-4: -You may not think it’s a big deal when you breathe in dust, but for some people, it could bring on a lung disease called hypersensitivity pneumonitis. It’s an allergic reaction to particles in the dust, and it can cause symptoms like coughing and shortness of breath.

Detailed explanation-5: -Your respiratory system prevents harmful substances from entering your lungs by using: Small hairs in your nose that act as an air-cleaning system and help filter out large particles. Mucus produced in your trachea and bronchial tubes to keep air passages moist and help catch dust, bacteria and other substances.
