We just learned about the Nostril.
Another part of the nose is the Nasal Septum.
This is what splits the nose into a left and right nostril.
It is made up of different parts, with some of it cartilage and some of it bone.
Sometimes if there is a nose injury a person can have what is called a deviated septum.
In that case the septum in the middle gets removed and they would only really have one big nostril.
