Nasal Mucous

Nasal mucus is produced by the nasal mucosa. Small particles such as dust, particulate pollutants and allergens, as well as infectious agents such as bacteria, are caught in the viscous mucus and are prevented from entering the respiratory system. Additionally, mucus aids in moisturizing the inhaled air and prevents tissues such as the nasal epithelia from drying out. Nasal and airway mucus is produced continuously, with most of it swallowed unconsciously, even when it is dried.

Increased mucus production in the respiratory tract is a symptom of many common illnesses, such as the common cold and flu. Similarly, hypersecretion of mucus can occur in inflammatory respiratory diseases such as respiratory allergies and asthma. The presence of mucus in the nose and throat is normal, but increased quantities can impede comfortable breathing and must be cleared through blowing the nose and nasal washouts.
