Let me share with you a comparison between Adaptive and Innate immune response.

 

AspectAdaptive or Acquired immune responseInnate immune response
SpecificityHighly specific to particular pathogens and antigens.General and non-specific in recognizing a broad range of pathogens.
MemoryExhibits immunological memory, leading to a faster and stronger response upon re-exposure to the same pathogen.Lacks immunological memory
Components·        B cells (antibody-mediated immunity)

·        T cells (cell-mediated immunity)

·        Composed of physical and chemical barriers

·        Phagocytic cells (e.g., macrophages)

·        Inflammatory responses

Time of ActivationSlower response timeRapid response within minutes to hours
ActivationActivated by exposure to specific antigens, often with the help of antigen-presenting cells (APCs).Activated by the presence of pathogens through pattern recognition receptors (PRRs).
FunctionMainly responsible for clearing infections, destroying infected cells, and providing long-term immunity.Provides immediate, but short-term, defense against a wide range of pathogens.
