mucous and nose hair.
As oxygen enters the nose, it passes through the nasal cavity where it is filtered, warmed, and humidified. This process helps prepare the oxygen for entry into the lungs where it can be absorbed into the bloodstream.
True Mucus helps moisten warm and filter the air as it enters the nose.
Mucus in the nose helps trap particles entering the respiratory system. The hairs/cilia of the respiratory system also filter incoming air.
Air enters the the respiratory tract through either the nose or mouth.
Oxygen enters through the nose but is involved with the Respiratory System.
In "Osmosis Jones," the nose shoots mucus at the dust that enters, trapping it to prevent it from entering the body. This is part of the body's defense mechanisms to filter out harmful particles and pathogens. Mucus helps keep the respiratory system clean and protects against infections.

as air enters through the nose the minute dust particles stick to the hair inside the nose. then air enters the wind pipe . as it travels down the wind pipe the oxygen present is absorbed by the lungs which in turn sends the purified air to the heart. the impure air or the co2 is sent back.
