The nasal cavity is divided into two by a septum made up of hyaline cartilage.
The nasal cavity is lined by the mucous membrane; it helps to adjust the temperature of the air we breathe in, to the internal body temperature.
The cavity has the olfactory nerve supply which regulates the sense of smell (olfaction).
The hair present in the cavity avoids the dust particles to enter the lungs during inhalation.
