Explanation:
Detailed explanation-1: -Because the adaptive immune system can learn and remember specific pathogens, it can provide long-lasting defense and protection against recurrent infections.
Detailed explanation-2: -The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
Detailed explanation-3: -Immune memory is a function of specificity and longevity-the ability of antigen-specific cells of the immune system to recognize and “remember” pathogens previously encountered and to produce a qualitatively and quantitatively different response (i.e., faster or more robust) than the first encounter.
