Nasal Passages
Nasal passages are the hollow tubes in the nose where air passes through. They are important to the human body's respiratory system as they help filter, clean and humidify incoming air before it enters the lungs. Nasal passages also produce mucus that traps and clears out dirt, bacteria and other foreign substances. This helps to prevent infections of the lungs and respiratory system, which can cause a variety of illnesses and health conditions. In addition, the nasal passages play an important role in the sense of smell, ensuring that odours are detected and identified.
