Relating to the nose or nasal cavity. In anatomy, it describes structures associated with breathing, smell, and the filtering of air before it reaches the lungs.
From Latin 'nasus' meaning nose, with the suffix '-al' meaning relating to. The term has remained relatively unchanged since ancient times as physicians described nose-related conditions.
Your nasal cavity processes over 10,000 liters of air daily! It's equipped with tiny hairs called cilia that beat 1,000 times per minute to sweep out dust and germs - like having a microscopic cleaning crew working 24/7.
