The only place that these membranes have cilia is the upper respiratory tract. This upper part is called the mucocillary escalator. It helps to keep the lower tract sterile and remove mucus. You swallow this mucus and microbes and the strong acid in the stomach kills them. There are other openings to the outside, the oral cavity, urogenital canals and the digestive tract at the anus. All have mucus membranes. These protect the underlining tissues and entrap microbes as well.

What do white blood cells have to do with pathogens?
White blood cells protects us (humans) by preventing pathogens from entering the body.
How does cilia prevent pathogens from entering your body?
Cilia protect your body from pathogens up to a certain extent. The cilia in your lungs prevent dust particles and other such particles you breathe from entering your lungs by trapping them and sweeping them away. The cilia located on the cell membrane prevents certain substances from entering the selectively permeable cell membrane through that same manner. However, if you get a cut or something, cilia are not really going to protect pathogens from entering your body from that cut.
Is tears a chemical barrier against pathogens?
yes, tears prevent pathogens from entering the eye. when an irritation occurs the eye produces a salty liquid (tears) to clean the eye from any dust or pathogens. eyelashes also prevent pathogens and dust from entering. In terms of a chemical barrier, your tears contain the enzyme lysozyme which can disrupt the cell walls of gram-positive bacteria by digesting the peptidoglycan in them. This enzyme is also found in your saliva.

How are stomach acid and mucous as a defense against pathogen?
Stomach acid is a chemical barrier against pathogens. The low pH of the acid creates an environment in which pathogens are unable to survive and will often kill them. Mucous is a physical barrier against pathogens. It acts to trap pathogens to prevent them from entering the body any farther.
