Quizplus · Accepted Answer

All of the choices listed contribute to inhibiting colonization of the body by potential pathogens. Shedding of skin cells removes any microorganisms that may have attached to the skin. Movement of mucus by cilia helps to trap and remove microorganisms that may have been inhaled. Peristalsis aids in the movement of material through the gastrointestinal tract to prevent microorganisms from settling and colonizing. The flushing action of the urinary tract helps to remove microorganisms from the urinary system. Together, all of these mechanisms help to prevent the colonization of the body by harmful microorganisms.
