lymphocyte, type of white blood cell (leukocyte) that is of fundamental importance in the immune system because lymphocytes are the cells that determine the specificity of the immune response to infectious microorganisms and other foreign substances.

What leukocytes are not lymphocytes?

Lymphocytes mainly constitute T cells, B cells, and natural killer (NK) cells. Their most salient role is in immune system. Thus we can say: All lymphocytes are leukocytes but all leukocytes are not lymphocytes. are the T cells, B cells, and natural killer (NK) cells.
