cilia
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.
I think you are referring to your tonsils, as you do not have lungs in your throat.
The cavity lined with cilia is the respiratory tract, including the nasal passages, trachea, and bronchi. Cilia help to sweep mucus and trapped particles out of the airways, protecting the lungs from harmful substances.
some cells in this lining secrete a sticky liquid called mucus, which traps particles of dirt or bacteria that are breathed in. Other cells are covered with timy hair-like structures called cilia. It sweeps the mucus and trapped particles out toward the mouth.
from nose through airway in throat into lungs
Someone who has drowned would not have air trapped in their lungs.
Mucus and bacteria are wafted away from the lungs primarily by the action of cilia, which are tiny hair-like structures lining the respiratory tract. These cilia beat in a coordinated manner to move mucus, which traps pathogens and debris, upward toward the throat, where it can be swallowed or expelled. This process is a crucial part of the respiratory system's defense mechanism, helping to keep the airways clear and prevent infections.
The trachea is lined with ciliated pseudostratified columnar epithelium to facilitate the movement of mucus and trapped particles out of the respiratory tract. The cilia beat in a coordinated manner to propel mucus, which traps dust, pathogens, and other debris, toward the throat for swallowing or expulsion. This structure enhances the respiratory system's ability to keep the airways clear and protect the lungs from infection and irritation. Additionally, the columnar shape of the cells allows for efficient absorption and secretion, further supporting respiratory health.
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.

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.
