PATHOLOGY

Detailed explanation-1: -Unlike innate immune responses, the adaptive responses are highly specific to the particular pathogen that induced them. They can also provide long-lasting protection.

Detailed explanation-2: -The secondary response of B-and T cells following subsequent encounter with the same antigen is more rapid due to the activation of previously generated memory cells. This has quantitative and qualitative differences from the primary response.

Detailed explanation-3: -The secondary immune response is one of the most important features of immune systems. During the secondary immune response, the immune system can eliminate the antigen, which has been encountered by the individual during the primary invasion, more rapidly and efficiently.

Detailed explanation-4: -Adaptive, or specific, immunity develops over your lifetime. Adaptive immunity has a memory component that primes the body to respond to a second instance of infection by the same pathogen more rapidly and more effectively than the first time it occurred.
