Detailed explanation-1: -The classical roles of respiratory mucus are to maintain the hydration of the respiratory tract and to act as a protective barrier against the external environment by trapping particulate matter, including pathogens.
Detailed explanation-2: -Your trachea is made of thick rings of cartilage. A substance called mucosa lines this cartilage. Mucosa produces mucus, which traps dust, allergens or other particles to keep them from traveling to your lungs.
Detailed explanation-3: -It serves as a lubricant to keep tissues from drying out. It’s also a line of defense. “Mucus is very important for filtering out materials that you breathe in through your nose, such as dust and allergens and microorganisms, ‘’ says Dr. Andrew Lane, an ear, nose, and throat expert at Johns Hopkins University.
Detailed explanation-4: -The mucus layer traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs. Cilia beat more than 1, 000 times a minute, moving the mucus that lines the trachea upwards about 0.5 to 1 centimeter per minute (0.197 to 0.4 inch per minute).
Detailed explanation-5: -The major function of the mucus is to limit bacterial contact with the epithelium and transport bacteria distally [26].
