The nose is a part of the respiratory system and is involved in several important bodily functions:
- Allows air to enter your body.
- Contributes to how you look and how you sound when you speak.
- Filters and cleans air to remove particles and allergens.
- Provides a sense of smell.
- Warms and moistens air so it can move comfortably into your respiratory system.
- Acts as a filter to remove harmful agents through the action of cilia (tiny hair-like structures) and mucus.
The nose is also responsible for facilitating the breathing process, filtering and conditioning the air we inhale, and enabling our sense of smell. It is a complex structure made up of five main parts: external meatus, nasal passages or cavities, septum, sinuses, and olfactory receptors.
