Nasal Cavity
Hollow space behind the nose
The nasal cavity is a part of the respiratory system that is located within the nose. It is responsible for the initial filtration, warming and humidification of the air that we breathe in.
The nasal cavity is made up of a series of complex structures, including the nasal conchae, the septum and the underlying bones. The nasal conchae are curved bony structures that project from the lateral walls of the nasal cavity. They are covered with a mucous membrane, which helps to trap and filter out any airborne particles.
The septum is a thin wall made up of cartilage and bone that separates the nasal cavity into two sides. The septum can sometimes become deviated or damaged, leading to difficulty breathing through the nose.
The walls of the nasal cavity are lined with a mucous membrane that contains cilia – tiny hair-like projections that help to move the mucus and any trapped particles towards the back of the throat, where they can be swallowed or coughed out.
The nasal cavity is an important component of the respiratory system, as it helps to protect the lungs from harmful pollutants and particles that can be present in the air we breathe in. Any inflammation or blockage in the nasal cavity can lead to issues with breathing, and may need to be addressed by a healthcare professional.
