The body region where a ciliary escalator to sweep microbes trapped in mucus away from that body site is the skin. respiratory tract. digestive tract. urinary tract. eyes.

It is in the respiratory tract. The respiratory tract is a air passage formed by the nose, mouth and throat. Since mucus is found in the nose, it is safe to assume the respiratory tract sweeps the microbes away from the body. A urinary track is in the lower area of the body, the digestive tract handles food not microbes and the eyes and skin do not have any relationship with mucus.
