Question

Which of the following is not a lymphocyte?
A) NK cells
B) plasma cells
C) memory T cells
D) macrophages
E) suppressor T cells

Accepted Answer

Macrophages are not lymphocytes. They are a type of phagocytic white blood cell known as a monocyte, which is involved in the innate immune response. Lymphocytes, on the other hand, are involved in the adaptive immune response and include NK cells, plasma cells, memory T cells, and suppressor T cells.
