microbes
epiglottis a flap that closes the opening to the

microbes to be swallowed instead of
to the lungs
microbiota barrier normal microbiota that protects against
invasion of potential pathogens

How does lysozyme kills bacteria by destroying their cell walls
work
acid/low pH kills microbes in the stomach, vagina,
bladder, and on skin
bile a digestive molecule that kills microbes in
the small intestine
Interferons are certain white blood cells and tissue cells
produced by
what are interferons proteins
what do interferons virally infected infected cells can

healthy neighboring cells from
multiplication
