the adaptive immune response involves physical barriers and nonspecific processes, whereas the innate immune response relies on the actions of B and T lymphocytes.

the adaptive immune response targets specific immunogens and remembers them, mounting an even stronger response on subsequent encounters, whereas the innate response is nonspecific and has no memory.

B and Tymphocytes can each target multiple proteins, whereas the innate response targets only a single type of antigen.

the innate immune response targets a specific immunogen and remembers it to mount an even stronger response on subsequent encounters with that immunogen, whereas the adaptive response is nonspecific and has no memory.
