The nasal septum is a wall made of bone and cartilage that separates the two sides of the nasal cavity. This nasal wall is covered by a mucous membrane.

SureHire explains nasal septum

The nasal septum separates the nose into two airways. The posterior portion of the septum is a thin skeletal frame, the front is made of cartilage. The nostrils are formed by the nasal septum's division of the nasal cavity. Exposure to chemicals such as calcium oxide or chromium can cause severe damage including ulceration or perforation to nasal septum. Employers are obligated to ensure that such chemical exposures are limited and that proper safety equipment is provided and safe handling procedures are implemented to protect employees from exposure. Defects in the nasal septum may lead to problems such as sleep apnea. Nasal deformities may also make fitting respiratory equipment more challenging.
