Quizplus · Accepted Answer

Lymphocytes exist in the greatest variety in the immune system, including B cells, T cells, and natural killer (NK) cells. B cells produce antibodies, while T cells can be further divided into helper T cells, killer T cells, and regulatory T cells. NK cells are involved in the innate immune response. Monocytes and macrophages are similar cells, with monocytes being the precursor cells that differentiate into macrophages once they enter tissues. Red blood cells (RBCs) are not considered part of the immune system.
