So they have extensive endoplasm reticulum that essentially forms many, many antibodies. And these antibodies that are formed by the plasma cell are specific and they complement the antigen that the B lymphocyte initially was bound to. And because we have many, many different types of plasma cells we have many different types of antibodies that are produced for each one of these different antigens that came from each one of these different types of pathogens. Now, what exactly is the purpose of these antibodies and what are these antibodies in the first place? Well, antibodies are specialized proteins. They are also known as immunoglobulins immune means immunity and globulants mean protein.
