MICROANATOMY

Detailed explanation-1: -The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.

Detailed explanation-2: -Mucus and cilia are a primary defense mechanism for the lungs. If there is a problem with either the mucus or the cilia, the airways may become blocked and the harmful germs and particles can be trapped in the lungs, causing damage.

Detailed explanation-3: -Mucus has an important role in your lung’s immune response because it traps irritants in your airways and helps allow your body to expel them through coughing. This helps protect you from infection.

Detailed explanation-4: -Cilia propel a liquid layer of mucus that covers the airways. The mucus layer traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs.

Detailed explanation-5: -The cilia in the respiratory tract help move debris like microbes and dust out of the lungs.
