Each nostril functions as an entry point to a nasal cavity where inhaled air is filtered and prepared for the lungs.
Nostril Function Explained
Here's a breakdown of how nostrils work:
-
Air Intake: Nostrils allow air to enter the respiratory system when you breathe.
-
Filtering: Inside the nostrils are tiny hairs called cilia. These cilia trap dust, pollen, and other particles, preventing them from reaching the lungs.
-
Passage to Nasal Cavities: Each nostril leads to a separate nasal cavity.
-
Nasal Cavity Preparation: The nasal cavities are lined with mucus membranes and respiratory epithelium cells. The mucus moistens the air, while the respiratory epithelium further filters and warms the air before it travels to the lungs.
In summary, your nostrils are the first line of defense for your respiratory system, filtering and preparing the air you breathe before it enters your lungs.
