Nasal Mucosa:

The entire inner cavities of the nose: airway cavities + all three pairs of turbinates + the sinus cavities, on both sides, are covered with a thick layer of tissue rich with blood vessels and central nervous system nerve endings, called – Nasal Mucosal Tissue.

But only the turbinates have significant erectable capabilities, because of the size and thickness of their nasal mucosal tissue (below the epithelium layer) – the “Lamina Propria” - which is very similar in expansion capabilities to other erectable tissues of the body, such as the penis and the clitoris. The turbinates have the capacity to shrink to the size of the diameter of their supporting bone, and to expand to fill in the entire nasal airway cavities, when needed. Of course – harboring such a potential means that the turbinates have a very rich blood supply net of arteries and veins, with nerve endings connected directly to the CNS (central nervous system).

The respiratory epithelium layer supports the cilia – which is a fine exterior layer of what looks like a blanket of tiny fine hairs, which move in a wave-like formation – that is known as the “cilia-beat”. The cilia “beats” around 250 times a minute and is responsible for capturing the potentially harmful airborne particles (dust, germs and viruses, etc’) allowing them to be trapped in the mucous secreted from the mucous producing glands (the “goblet” and “serum” cells located in the epithelium layer). The debris is pushed towards the nasopharynx and swallowed through the eusophgus into the stomach. It takes the healthy cilia around 20 minutes to push the trapped particle/organism from the anterior nares to the nasopharynx). On a normal day the nasal mucosa will produce about ¾ of a liter of mucous, that kills the invading microorganisms, enables the cilia to push the debris away smoothly, and humidifies the inspired air.
