They don't the only way to keep dirt from going into your throat is to breathe through your nose where your nose hair and mucus provide traps for dirt.
Yout throat cells have tiny hairs which trap and prevent dust and dirt from going into your body, you also have these cells in your nose too.
They do not stop it but the mucus and motion of the cillia remove said microbes and dust should they get into the lungs.
The cilia on their surface trap dust and microbes, then pass the trapped substances along with mucus to the throat, where they can then be swallowed. This then protects the lungs.
Epithelial cells I think.... or Cilia, no i think Cilia are hairs!
The slimy secretions in the lungs that protect it from dust and infectious agents are called mucus. Mucus traps particles like dust and pathogens, preventing them from entering deeper into the lungs. The cilia in the respiratory tract then move the mucus upwards so it can be expelled from the body.

The hairs in the nose help filter out dust, pollen, and other particles from the air we breathe. The epithelial lining helps trap harmful particles and also produces mucus to moisturize and protect the nasal passages. Together, these structures help keep the respiratory system healthy by preventing irritants from entering the lungs.
Epithelium Cells are usually flat and cover the surface of organs. There is a special type of epithelial cell. Millions of epithelical cells line our windpipe and help stop dust travelling all the way into our lungs. Once the dust has been stopped, they also push it back up the windpipe to the throat.
Cells in the nose and throat that trap dust are primarily ciliated epithelial cells and goblet cells. Ciliated epithelial cells have hair-like structures (cilia) that move in a coordinated manner to push mucus, which traps dust and other particles, out of the airways. Goblet cells secrete mucus, providing a sticky surface that captures debris and pathogens. Together, these cells play a crucial role in protecting the respiratory system from inhaled irritants.
cillliated epillithial cells or cillia for short, they clean dust and mucus from our lungs
When you inhale, the air you breathe in is cleaned by cilia in your trachea. This helps remove dust and other pathogens from the air when it is on its way to your lungs
The lining of the lungs is coated by a layer of mucus produced by goblet cells and respiratory epithelial cells. This mucus traps dust, pathogens, and other particles, helping to protect the lungs from infection and irritation. However, exposure to pollutants, smoking, and certain infections can lead to inflammation and diseases such as chronic obstructive pulmonary disease (COPD) and asthma, where the normal function of this protective lining is compromised.
