role of C5B6789
LYSIS
the process whereby WBC move from the circulatory system into the tissue (any

which of the following describes innate immunity?
immediate
the membrane attack complex of complement is made up of
C5bC6789
cells participating in ADCC must have the surface marker ______ to bind to
immunoglobulin G
CD 16
how does the normal human microbiota protect us from infection?
compete with potential pathogens for nutrients
