The lay person's term for that is phlegm.

Actually, the body region where a ciliary escalator helps to sweep microbes trapped in mucus away is the respiratory tract, specifically in the lungs. The cilia lining the respiratory tract beat in a coordinated manner to move mucus and trapped microbes up and out of the airways.
cilia
Ciliated epithelial cells produce mucus, which helps to trap and remove foreign particles and pathogens from the respiratory tract. The cilia on the cell's surface then move the mucus along to be expelled or swallowed.
Yes, the trachea is the first structure classified as a part of the lower respiratory tract.
Once a fungus is inhaled, it will multiply, either in the upper or lower respiratory tracts. As the fungi multiply, it will interfere with breathing, causing an overabundance of mucus. An upper respiratory tract infection includes the common cold and laryngitis. Lower respiratory tract infections are usually more serious and include bronchitis and pneumonia, both of which can be fatal.
The mucus of the trachea is expelled from the respiratory tract through a process called mucociliary clearance. Cilia, tiny hair-like structures lining the trachea, move the mucus upwards toward the throat. Once it reaches the throat, the mucus can be swallowed or coughed out. This mechanism helps keep the airways clear of dust, pathogens, and other debris.
Mucus is pushed to the throat from the respiratory tract, primarily through the action of cilia—tiny hair-like structures on the surface of respiratory cells. This process helps trap and clear dust, pathogens, and other particles from the airways. Once in the throat, mucus can be swallowed or expelled through coughing. Additionally, mucus in the digestive system aids in lubrication and protection.
Mucus and cilia. The dirt and other impurities that enter the respiratory tract are trapped by the mucus, in order not to enter the lungs and its structures. But the accumulation of too much mucus in the trachea would impede us from breathing, so the cilia sweep the mucus out of the trachea.
The mucus layer protects the respiratory tract by trapping bacteria and dust, not allowing them to enter the body. Mucus filters the air during inhalation and keeps the tissues from becoming too dry.
Acute= severe. Lower Respiratory Tract= Respiratory system below the larynx. This refers to a pneumonia or a bronchitis.
