The internal structure of the nose is quite intricate. The nose serves as the respiratory tract’s opening and also contains the olfactory organ. It also warms, moistens and also filters foreign debris from inhalation. The cavity of the nose is separated from one another by the septum – a cartilaginous wall. The nose is also lined with mucous membranes which trap foreign particles such as dust.
