what are the body's nonspecific defenses against invading pathogens

Question

anonymous · Answer

everything that is not an antibody is probably nonspecific.  Antibodies are very specific.  So defenses against pathogens include the barrier of the skin and fever.  There may be others, but those two come to mind.

And some white blood cells may be nonspecific too.

The differentiation you're looking for is between the innate and adaptive immune systems. The innate immune system is the base line defense against pathogens. Adaptive comes after a pathogen has already been previously introduced to the system.
