Click and drag on elements in order Beginning with growth of the pathogen at the top, place the events in order that can lead to a rapid exit of the pathogen.
1.- intestinal pathogens grow in intestinal mucosa 2.-inflammation results 3.-motility (irritability) of the bowel increases 4.-increased peristalsis results in diarrhea 5.-fluid stool provides rapid exit for pathogen
