Which type of immunity is capable of remembering a past immune response?
A
Adaptive immunity
B
Passive immunity
C
Innate immunity
D
Non-specific immunity
Verified step by step guidance1
Understand the different types of immunity: Innate immunity is the body's first line of defense and is non-specific, meaning it does not remember past infections. Adaptive immunity, on the other hand, is specific and has the ability to remember past infections.
Recognize that adaptive immunity involves the activation of lymphocytes (B cells and T cells) that can remember specific pathogens through memory cells.
Consider passive immunity, which is acquired through the transfer of antibodies from another source, such as maternal antibodies or immunoglobulin therapy, and does not involve memory.
Differentiate between innate and adaptive immunity: Innate immunity is immediate and non-specific, while adaptive immunity is slower to respond but specific and capable of memory.
Conclude that the type of immunity capable of remembering a past immune response is adaptive immunity, due to its ability to form memory cells that recognize and respond more effectively to previously encountered pathogens.
