Ciliary action in the trachea helps to clear mucus and trapped particles, such as dust and pathogens, from the respiratory tract. The cilia, tiny hair-like structures lining the trachea, beat in a coordinated manner to move the mucus upward toward the throat, where it can be swallowed or expelled. This mechanism is crucial for maintaining respiratory health and preventing infections by keeping the airways clear.
