How exactly B lymphocytes cells do defence?

When a foreign substance enters the body, the B cells are activated. They recognize the substance as foreign, multiply, then differentiate into plasma cells and memory cells. The plasma cells produce proteins known as antibodies, which attach to the substance and neutralize it, much in the way an acid neutralizes a base in a chemistry lab experiment. Foreign substances that can cause the body to produce antibodies are known as antigens.
