And it's the plasma cells that will begin to produce antibodies specific to these antigens that are brought to these B lymphocytes by our dendritic cell and other cells such as our macrophage. So basically, our plasma cells produce these antibodies that are released into our blood system and then these antibodies can bind to these specific antigens. And once they bind onto the antigens they label them for destruction by cells like macrophages, neutrophils and other cells of our body. Now, memory cells are those cells of our body that remain with us for the duration of our lifetime. And they keep a copy of this antigen in case reinfection ever takes place. And if reinfection does take place, they elicit a secondary immune response that is much quicker and more efficient than a primary immune response.
