The Mucociliary Clearance System
The Mucociliary Clearance System is part of the body’s natural defence mechanism which provides protection against mild upper respiratory tract infections. It is the first line of defense against inhaled pollen, dust, germs and allergens.
How does the Mucociliary Clearance System work?
When your nose and nasal system is functioning optimally you have a thin layer of mucus which coats your nasal membranes. Your nose is also equipped with microscopic hairs called cilia hairs.
The thin mucus traps the inhaled germs, dust and allergens and the tiny cilia hairs dip into the mucus and push the mucus down the back of your throat towards your stomach. In your stomach the germs, dust and allergens are destroyed by the strong stomach acid.
Maintenance of the Mucociliary Clearance System is at the forefront of nasal health because when the system is impaired it can result in ailments such as hayfever and sinusitis.
How does the Mucociliary Clearance System become impaired?
Thickened, dry mucus:
When nasal mucus thickens, it is difficult for the cilia hairs to move the mucus. The cilia hairs are fragile too, so they often get stuck in the mucus and can break off. Cilia hairs take approximately two weeks to regrow and during this time the Mucociliary Clearance System is impaired.
The most common cause of nasal congestion is the temporary swelling of the nasal passages due to colds or allergic reactions. Along with this swelling our nose tends to create “extra” mucus. This mucus often clogs the nasal passages making it harder for the cilia hairs to move the mucus down the throat. This can also cause them to break off and thereby impair the important Mucociliary Clearance System.
What can you do to ensure the health of your Mucociliary Clearance System?
It is important to keep the nasal mucus thin, less sticky and easier to move. By thinning the mucus and keeping the cilia hairs mobile your body can move the inhaled pathogens, dust and allergens to your stomach where they can be destroyed by stomach acid.
The FESS® range of nasal sprays are designed to thin the nasal mucus and to wash away allergens, dust and pollutants, By using a FESS nasal spray everyday you can help your body to maintain better nasal health.
