Detailed explanation-1: -Breathing in through the nose warms and humidifies the air that is breathed in. Nose hairs help to trap any particles of dust. The warmed air enters the lungs through the windpipe, or trachea.
Detailed explanation-2: -Air enters the respiratory system through the nose or the mouth, then travels down a pathway to the lungs. 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-3: -Sinuses, hollow bones of the head, help to warm and humidify the air, while hairs in the nose filter it. The air passes through the pharynx at the bacN of the throat and the larynx, which contains the vocal cords.
Detailed explanation-4: -The THROAT collects incoming air from your nose and mouth then passes it down to the windpipe (trachea). The WINDPIPE (trachea) is the passage leading from your throat to your lungs. The windpipe divides into the two main BRONCHIAL TUBES, one for each lung, which divides again into each lobe of your lungs.
Detailed explanation-5: -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.
