Question 3

Predict the consequences of non-functional cilia in the respiratory airways.

Accepted Answer

Cilia lining the respiratory tract beat in a synchronized manner to move sticky mucus and trapped dust particles toward the throat and away from delicate respiratory surfaces. This cleansing action is lost if the cilia are damaged or immobilized by heavy smoking or some metabolic problem, and the irritants will no longer be removed. As a result, chronic respiratory infections develop.
