Lymphocytes in human circulating blood are approximately 80 to 90 percent T cells, shown in the figure below, and 10 to 20 percent B cells. Recall that the T cells are involved in the cell-mediated immune response, whereas B cells are part of the humoral immune response.
A lymphocyte is a type of white blood cell in the immune system of jawed vertebrates. Lymphocytes include natural killer cells (which function in cell-mediated, cytotoxic innate immunity), T cells (for cell-mediated, cytotoxic adaptive immunity), and B cells (for humoral, antibody-driven adaptive immunity). If your doctor tells you that you have B-cell lymphoma, it means you have a cancer that forms in white blood cells called lymphocytes.
