So these cells are responsible for producing a type of biological immune or defense molecule known as the antibody. So antibodies are essentially these proteins that circulate throughout our blood and they can attach and recognize the antigens of bacterial cells and other pathogens. And by binding to these antigens, what the antibodies do is they help our immune system initiate these defense mechanisms that ultimately kill off those harmful pathogens. So these are the two different types of divisions of the immune system or two responses. We have the innate immune response that takes an effect immediately and we have the quiet immunity response that usually takes several days to actually take an effect. Now, innate immunity is not learned by the body.
