Detailed explanation-2: -There are four characteristics of adaptive immunity: antigenic specificity, diversity, immunologic memory and ability to distinguish between self and non-self. An immune response involves Lymphocytes (B-cells and T-cells) and antigen presenting cells (macrophages, B-cells, and dendritic cells).

Detailed explanation-3: -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.
