The importance of specificity and memory in the acquired immune system is cellular immunity which helps to fight pathogens called T cells individually. It helps to fight cells foreign, cancerous and host, but it also attacks transplanted tissues. Humoral immunity involves antibody-mediated B cells that are never involved in the battle. They release antibodies against bodily fluids, move away and send chemicals to attack pathogens, meaning they are not directly involved in the battle. When you are exposed to a variety of pathogens, you remember them and maintain acquired immunity. This means that the body has memory cells, which give it immunity against future exposure to the
