The mucus layer protects the respiratory tract by trapping bacteria and dust, not allowing them to enter the body. Mucus filters the air during inhalation and keeps the tissues from becoming too dry.
The mucus that lines the respiratory system helps to keep you healthy in a few ways. It traps pollutants like dust, bacteria, and viruses helping to keep then from entering the lungs. In the event that some pollutants reach the deeper parts of the lungs, the sticky mucus helps to cough them out.
To prevent pollen, dust and germs from entering.

Four barriers that protect humans from pathogens include the mucus of the upper respiratory system, the acid mantle of the skin, the stomach acid in the digestive system, and the cervical mucus of the female reproductive system. There are also celular barriers via the immune system that prevent infection.
The respiratory system has a number of nonspecific defenses against disease. The hairs of the nose trap dust and pathogens. Mucus in the upper and lower respiratory system traps foreign bodies and pathogens. The cilia constantly move the mucus with this trapped material out of the system. The cough and sneeze reflexes also offer protection.
the nose belongs to the respiratory system.
