The erectile tissue in the nose helps to regulate airflow by increasing in size, directing air through one nostril at a time.
The Nasal Cycle Explained
The presence of erectile tissue within the nose isn't about sexual arousal, but rather about something called the nasal cycle. This cycle refers to the natural congestion and decongestion of the nasal passages that occurs in a cyclical pattern.
How it Works
- Erectile Tissue Expansion: As explained in the reference, our bodies deliberately send more blood to the erectile tissue located between the nostrils.
- Increased Size & Airflow: This increased blood flow causes the erectile tissue to swell, which in turn increases its size.
- Direction of Air: This swelling effectively directs the majority of the airflow through one nostril.
- Alternating Nostrils: After a few hours, the process reverses and the airflow switches to the other nostril. This natural cycle ensures that each nostril receives adequate rest and moisturization.
Why is the Nasal Cycle Necessary?
The nasal cycle is important for several reasons:
- Moisturization and Protection: It allows one nostril to rest and moisten while the other does the work of filtering and humidifying the air. This prevents the nasal lining from drying out and becoming damaged.
- Enhanced Olfactory Function: Some research suggests that the alternating airflow may allow each nostril to detect different odors more effectively, enhancing our sense of smell.
- Preventing Irritation: The cycle prevents continuous airflow from irritating one nostril for an extended period.
Key Takeaways
| Feature | Description |
|---|---|
| Erectile Tissue | Located between the nostrils |
| Function | Regulates airflow by swelling and directing air through one nostril at a time |
| Nasal Cycle | Natural pattern of congestion and decongestion, typically alternating every few hours |
The erectile tissue in the nose, therefore, is a crucial part of the nasal cycle that aids in proper respiration, moisturization, and possibly even enhances our sense of smell, as highlighted in the provided reference: Our bodies deliberately send more blood to an erectile tissue between the two nostrils to increase its size and direct the air flowing through one of the nostrils. After a few hours, the airflow switches to the other nostril.14-Sept-2018
