GENERAL HISTOLOGY

Detailed explanation-1: -This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to “remember” germs, so the next time a known germ is encountered, the adaptive immune system can respond faster.

Detailed explanation-2: -Memory is a characteristic recognized within both the innate and adaptive arms of the immune system. Although the mechanisms and properties through which innate and adaptive immune memory are induced are distinct, they collude to improve host defense to pathogens.

Detailed explanation-3: -Then, the components of acquired immunity learn the best way to attack each antigen and begin to develop a memory for that antigen. Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its hallmarks are its ability to learn, adapt, and remember.
