Question : What plays an important role in primary and secondary response ?

Answer»

Solution :The primary and secondary response are CARRIED out with the help of two special types of LYMPHOCYTES present in our body that is B-lymphocytes and T-lymphocytes.
B-lymphocytes produce an ARMY of PROTEINS in response to pathogens into our blood to fight with them. These proteins are CALLED antibodies.
T-lymphocytes themselves do not secrete antibodies but help B-lymphocytes to produce antibodies.
