0:00so in this slide here what we're looking
0:03at is what's called specific defenses so
0:06in your immunity within your lymphatic
0:09system your body has a certain number of
0:11T cells that it has produced and a
0:14certain number of B cells now remember
0:16our immunity is inherited and it we have
0:20our immunity for life at Birth it does
0:24grow throughout the thymus and the T
0:26cells that are released but at the
0:28around adolescence or puberty remember
0:31the thymus it has no purpose
0:34so your T and your B cells are your main
0:37fighter cells the responsibility of your
0:40T cells are to attack specific cells
0:43specific cells meaning uh cancer cells
0:47meaning HIV cells T cells already are
0:51made up genetically to fight specific
0:54illnesses whereas B cells B cells have a
0:59bigger responsibility to make antibodies
1:02to then recognize antigens and fight
1:04them and so an example of B cells and uh
1:08would be a vaccination if you think
1:11about having a flu vaccine you are not
1:14born with the immunity to necessarily
1:17fight off the flu not only that but
1:20remember the flu changes from year to
1:22year which is why we need to continue to
1:24have boosters so what happens is you go
1:27into the doctor's office and you have
1:29your flu shot or your flu vaccination
1:31your body then recognizes through the
1:35antibodies that you've been given your B
1:38cells start to recognize that and adapt
1:40that behavior so the nice thing is now
1:43now you've been vaccinated against the
1:46flu you come in contact with someone who
1:49has the flu not going to be that big of
1:52a deal for you because your body has
1:54already started to make those memory
1:57cells or antibodies so that if it does
1:59come against the flu which now it has it
2:01now knows what to do and so it doesn't
2:04mean that you won't necessarily get the
2:07flu or you won't get covert or you won't
2:09get pneumonia you very well may still
2:12get those particular uh
2:15uh invasions in your body however the
2:18the symptoms will be far less than they
2:21would have been had you not been
2:22vaccinated and again it's because your
2:25body has the ability to make those
2:27antibodies when your body's at its
2:29healthier state to remember what it
2:32needs to do if in fact it has to draw a
2:35line of defense on your behalf so T
2:38cells attack the cells B cells make
2:40antibodies also within the antibodies
2:43you have a term that's called
2:46immunoglobulins and then you
2:48immunoglobulins is just another form of
2:51an antibody and it is an antibody that
2:55is produced to respond to specific
2:57antigens we heard a lot about
3:00immunoglobulins during the covet uh
3:03phase that we went through the whole
3:05pandemic for the past three years uh and
3:08this is now a known treatment because
3:10while we haven't found a cure
3:12necessarily for covid-19 we have been
3:16able to develop antibodies which are
3:18produced to specifically attack the
3:21components of covid and so this is now a
3:25treatment that is in play it's produced
3:28by white blood cells to help eliminate
3:30disease-causing microbes from the body
3:32and it does this by directly destroying
3:35pathogens or by blocking them from
3:38infecting cells we see this with HIV as
3:42well
