What is the function of the cilia cell?

Cilia cells play an important role in protecting the lungs from damage. They are tiny hair-like structures that line the respiratory tract. Their primary function is to move mucus and trapped particles, such as dust and pathogens, out of the airways. This movement helps to keep the air passages clear and prevents harmful substances from reaching the lungs, which could lead to infections or other respiratory issues.

The presence of cilia is a critical defense mechanism because it ensures that the lungs remain free from contaminants that could cause irritation or disease. When cilia function properly, they contribute significantly to respiratory health by maintaining clear airways and assisting in the overall process of filtering out unwanted materials inhaled with the air.
