Antibodies and Antigens

First,  the body works awesome when it comes to antigens and antibodies.  The body works by first an antigen has to come into the body and then the immune system does it job by building an antibody to fight off the antigen.  Then when it is built it attacks the antigen.  The B lymphocytes are stored in the bone marrow which is used in the process of the making of the antibody to kill the antigen.  Afterwards, the B lymphocytes stay around and protect against anymore of the antigen that comes in and if there is anymore then it will make more antibodies.
