The gap between your nostrils is primarily formed by the septum, a structure made of cartilage and bone.
The septum acts as the dividing wall between your nostrils. Here's a breakdown:
- The Septum: This is the "center line" that separates the left and right nostrils. It's not just empty space, but a physical structure made of cartilage and bone.
- Function: The septum provides structural support to the nose and allows for independent airflow through each nostril. This means if one nostril is blocked, you can still breathe through the other.
Occasionally, the septum can develop a hole (perforation).
In summary, what appears to be "the gap" is actually filled by the nasal septum.
