Document Summary
Upper respiratory tract nasal and oral cavities, larynx. * the nasal cavity is lined by a highly vascular mucous membrane. The nasal cavity produces mucous to trap foreign particles. The nasal cavity is important for warming air before it enters the lungs (done by vascular supply) * the vestibule is the front of the nasal cavity that is lined by skin and hair. * the nasal septum separates the nasal cavity into two halves. * on the lateral and medial wall of the nasal cavity the mucosa is split into an olfactory area and a respiratory area. The olfactory area is the top 1/3 and it has sensory receptors for smell that sit on this mucous. This olfactory nerve continues to become the first cranial nerve to take information about smell to the brain). The respiratory area is the rest of the space and it is characterised by very ciliated epithelium that encourages/helps mucous move out of the airway)
