Explain the Function of Nose

You would agree that one of the most prominent features of the face is the nose. The nose is the first of the respiratory organs through which we respire, i.e. inhale oxygen and exhale carbon dioxide. What are the functions of the nose? We all are familiar with the functions of the nose. The nose:

  • Acts as a respiratory passage through which the incoming air passes, and
  • Warms, moistens and filters the air. The air becomes warm as it passes through the nose. It is moistened by contact with the moist mucous. The air gets filtered because the dust particles and other impurities (in form of particulate matter) stick to the mucous. Hence, nose acts as a filter. The cilia of the mucous membrane waft mucous and the dust particles from the nose towards the throat.
