Explanation:
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: -The cilia in the respiratory tract help move debris like microbes and dust out of the lungs.
Detailed explanation-3: -Respiratory epithelium. The goblet cells secrete mucus, which forms a blanket over the tops of the ciliated cells. The regular, coordinated beating of the cilia sweeps the mucus up and out of the airways, carrying any debris that is stuck to it.
