Question

Quizplus · Accepted Answer

Having a system of adaptive immunity allows for a rapid defense against an antigen that has been previously encountered. This is because the adaptive immune system is able to recognize and respond to specific antigens, and can produce a quicker and more specific response upon subsequent exposure to the same antigen. This is in contrast to the innate immune system, which provides a more generalized defense against a wide range of pathogens but does not have the specificity or memory of the adaptive immune system.
