No, we do not have 4 nostrils.
While it might seem like we have a single nose with two openings, the reference provided clarifies that humans actually have two noses. Each of these "noses" leads to a nostril, serving as its own distinct pathway to the respiratory system. Therefore, we have two nostrils, not four.
Here's a breakdown:
- Each Nostril is a Separate Pathway: Although they work together, each nostril is independent in many ways, having its own opening into the nasal cavity.
- Functioning Together: While separate, both nostrils contribute to the overall respiratory process, working in tandem for breathing and smelling.
- Two "Noses," Two Nostrils: The reference emphasizes that we have "two noses," which inherently means two separate pathways, each with one nostril.
To further illustrate:
| Feature | Count |
|---|---|
| Eyes | 2 |
| Ears | 2 |
| Noses | 2 |
| Nostrils | 2 |
Therefore, the correct answer based on provided reference is that we have two nostrils, each connected to its own pathway within the nasal structure.
