1) Antigenic Specificity : It is highly specific; recognizes and targets specific antigens
2) Diversity : It has immense diversity of lymphocytes and receptors, enabling the immune system to detect pathogens never before encountered.
3) Immunologic Memory : It has stronger and more rapid response to an antigen encountered previously.
