Nose

Definition

The nose is a vital organ in the respiratory system responsible for the intake of air and the initial filtration of particles. It also plays a crucial role in olfaction and humidifying inhaled air.

5 Must Know Facts For Your Next Test

1. The nose filters out large particles and pathogens from the air using nasal hairs and mucous membranes.
2. Proper nutrition can support mucosal health in the nose, aiding its function to filter and humidify air.
3. Certain nutrients, like Vitamin C and zinc, are essential for maintaining nasal mucosal immunity.
4. Dehydration can impair the nose's ability to humidify incoming air, potentially affecting pulmonary wellness.
5. Nasal congestion can impede airflow, making it important to manage diet-related factors that might exacerbate inflammation or mucus production.
