The ciliated lining of the trachea and other tubes of the respiratory tract sweeps impurities up away from the lungs and towards the throat.
Cillia are small hairs that have the function of "sweeping" tubes in our bodies. The cillia in our lungs sweep dust and other impurities towards our throat. Usually at night and in our sleep we cough or clear our throat and swallow this mucous. Yuk, but keeps our lungs clean.
The tiny hairs in the lungs that sweep out dirt and mucus are called cilia. These hair-like structures help to keep the airways clear by moving debris upwards towards the throat where it can be swallowed or expelled.
I think you are referring to your tonsils, as you do not have lungs in your throat.
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.
Cilia in the respiratory tract help to sweep contaminated mucus out of the airways and move it towards the throat where it can be expelled or swallowed. This helps to clear the airways of bacteria, viruses, and other particles that may cause infection or irritation.
Cilia in the nasal cavity act as tiny hair-like structures that help to trap and remove harmful particles and pathogens from the air we breathe. They sweep these particles towards the throat where they can be swallowed or expelled, preventing them from entering the lungs and causing damage.
from nose through airway in throat into lungs
Cilia in the nose act as tiny hair-like structures that help to trap and remove harmful particles and pathogens from the air we breathe. The cilia move in a coordinated manner to sweep these particles towards the throat where they can be swallowed or expelled, thus preventing them from entering the lungs and causing damage.
The respiratory system is what system your lungs are apart of, and your throat, if it's the same as the esophagus, is apart of the digestive system.
