How is mucus removed?

Mucus is removed from the body primarily through the action of cilia, tiny hair-like structures lining the respiratory tract, which beat in a coordinated manner to move mucus upward toward the throat. Once in the throat, mucus can be swallowed or expelled by coughing. Additionally, nasal mucus can be cleared by blowing the nose. This process helps to trap and eliminate pathogens, allergens, and debris from the airways.
