1. In words, trace the path of air into the body. We breathe in air through our nose. The airs first stop is in the nasal cavities where there are large stiff hairs that filter the air that has dust in it so it doesnt get into our air passage. The nasal cavities are lined with mucous membranethat has plentiful capillaries. The Capillaries in the nasal cavities help moisten and warm the air. the muscous secreted by the mucous membrane helps traps dust and move it to the pharynx. We then breathe out the air and when it is cold outside we can see our breathe because the air is moistened.
