natural killer cell
It is not involved with the production of any specific type of lymphocyte
Nonspecific
B lymphocytes secrete free antibodies, which provide immunity to virusesT lymphocytes are coated with bound antibodies, they provide immunity to foreign cellsmacrophages generally eat debris, but when activated by lymphocytes they concentrate on eating whatever matches the type of antibody the lymphocyte makes
red blood cells
Lymphocyte
T cells are a type of lymphocyte in the body that are responsible for cell-mediated immunity. Basically this means they are not antibodies but are responsible for activation of phagocytes to fight off diseases.
We call this type of immunity adaptive---> natural----> active immunity. Here how it works: Adaptive immunity involves two classes of lymphocyte: B cells and T cells which work together in a coordinated system of adaptive immunity B cells-antibody-mediated (humoral) immunity T cells-cell-mediated (cellular) immunity Adaptive immunity occurs in a series of stages 1. Recognition of antigen (flu virus) 2. Activation of lymphocytes 3. Effector phase (immune attack) 4. Decline of antigen causes lymphocyte death (homeostatic balance) 5. Memory cells remain for later response if needed
