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: -Adaptive immunity develops in conjunction with innate immunity to eliminate infectious agents; it relies on the tightly regulated interplay between T cells, APCs and B cells.
Detailed explanation-3: -They present the new antigen using specific receptors on their cell surface called major histocompatibility complexes, or MHCs; typically type II. T cells detect this unique antigen/receptor presentation via specific receptors called T Cell Receptors (TCRs).
Detailed explanation-4: -The immune system can be classified into two subsystems: the innate and adaptive immune systems. In general, innate immunity is considered a nonspecific response, whereas the adaptive immune system is thought of as being very specific.
