PNB 2265-Immune System Study
Guide.
non-specific immune system - Answer generalized responses that help to support the
immune system, support imm. sys. function, recycle cells, and non-specifically destroy foreign
cells and materials
specific immune system - Answer protects against specific antigens; has the ability to
differentiate between self-antigens and foreign antigens
