adaptive immunity Flashcards
active or passive immunity
slow reponse
active
- LONG TERM immunity
- SLOW response
- immune system is CHALLENGE
active or passive immunity
antibody is readily available
Passive immunity
- SHORT TERM but IMMEDIATE response
- ANTIBODY IS READILY AVAILABLE
- immune system is NOT CHALLENGE
