The mucus that's produced in your respiratory tract has 3 important jobs:
MUCUS PROTECTS. Mucus moistens and warms inhaled air and keeps the mucus membrane cells and the little hairs called "cilia" lubricated. These little hairs line the top layer of mucus membrane cells. Cilia helps to remove inhaled particles that have gotten trapped by the mucus layer covering the cilia. They need to stay moist to do their job.
MUCUS ACTS AS A BARRIER. Mucus traps inhaled particles (like dust, allergens, bacteria, or viruses) and keeps them from getting deeper into your lungs. Mucus also keeps them from invading the cells lining your airway and entering your system. The cilia transport the mucus layer toward your throat, where it could either get spit out or swallowed.
MUCUS DEFENDS YOUR BODY. Mucus contains antibodies, enzymes, and proteins that work to help get rid of whatever's in the air you've inhaled that could make you sick.

The role of mucus in the nose is that it prevents the dust particles to enter our nose.
