All of these factors can prevent or limit colonization of the body by pathogens. The shedding of skin cells removes any bacteria or viruses that may have attached to the surface of the skin. The movement of mucus by cilia can trap pathogens and prevent them from entering the respiratory system. Peristalsis in the digestive tract helps move food and waste material through the system, limiting the amount of time pathogens have to colonize the area. The flushing action of the urinary tract helps to remove any pathogens that may have entered the body through the urinary system.
