Briefly describe the  cells of the immune system.

Solution
The major cells of the immune system are the WBCs called lymphocytes. Lymphocytes that are critical for immune reactions are of two types : B-cells and T-cells. 
B-cells produce anibodies in response to antigens and provide protection against the pathogens inside our blood.

 T-cells do not produce antibodies but help the B-cells to produce it.
