IMMUNOLOGY

Detailed explanation-1: -Adaptive immune responses are carried out by white blood cells called lymphocytes. There are two broad classes of such responses-antibody responses and cell-mediated immune responses, and they are carried out by different classes of lymphocytes, called B cells and T cells, respectively.

Detailed explanation-2: -This acquired response is called “adaptive” because it prepares the body’s immune system for future challenges (though it can actually also be maladaptive when it results in allergies or autoimmunity).
