(If the external barrier is breached, the second line of defense is the internal aspect
of the innate immune system, a collection of nonspecific cellular responses
(inflammation, production of interferon, ingestion of pathogens by phagocytes)
The internal aspect of adaptive immune system - ANSWER-The responses
described are not part of the adaptive immune system. Adaptive immunity is specific
to a particular antigen, not nonspecific.
Antibody-mediated immunity - ANSWER-it is a defense that employs B-cells to
create antibodies that tag pathogens for later destruction.
