ANATOMY

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 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-3: -Mucus acts as a physical barrier, trapping inhaled particles and pathogens, whilst cilia move both the mucus layer and fluid in the underlying periciliary layer.

Detailed explanation-4: -In respiratory tract, cilia helps in expelling the mucus and particles trapped in it, towards the pharynx.

Detailed explanation-5: -MUCUS PROTECTS. Mucus moistens and warms inhaled air and keeps the mucus membrane cells and the little hairs called “cilia” lubricated. MUCUS ACTS AS A BARRIER. MUCUS DEFENDS YOUR BODY.
