Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What do the cilia do?

A	Catch dust and microbes
B	Waft mucus and trapped dust and microbes up and out of the lungs
C	Help the cells lining the windpipe to move about
D	None of the above

Explanation:

Detailed explanation-1: -The mucus traps any bacteria or pathogens as they enter the lungs, and the cilia, located on the surface of ciliated epithelium, move in a synchronised pattern to waft the mucus up the airway to the back of the throat where it can be swallowed and any pathogens can be killed by the acidity of the stomach.

Detailed explanation-2: -Cilia line the airways and help move mucus up and out of the lungs [5].

Detailed explanation-3: -The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.
