0:00let's take a look today at What's called
0:02the lymphatic system now with your
0:04lymphatic system the lymphatic system
0:06works hand in hand with your immune
0:09system it does have what is known as the
0:12largest organ and that is your spleen it
0:15also consists of your thymus your lymph
0:17nodules lymph nodes interstitial fluid
0:21adenoids and tonsils primary function of
0:25the lymphatic system is to Aid in
0:27protecting your body against pathogens
0:30and some of the pathogens that our
0:32bodies can come against would be cancer
0:34bacteria parasites viruses and so on the
0:38lymphatic system works as a network of
0:41connecting vessels those vessels work
0:44within the lymphatic vessels the lymph
0:47nodes the lymph capillaries all work
0:49together and collecting what's called
0:51lymphatic fluid or lymph fluid that is
0:54distributed throughout the body that
0:56starts what's called your immune
0:58response
0:59first uh portion of the immune response
1:03is the inflammation that our body
1:05experiences that is done through the
1:08lymphatic system with the accumulation
1:10of what's called lymph fluid
1:13primary purpose is to Aid in removing
1:17pathogens also throughout the body you
1:19have lymph nodes and those lymph nodes
1:22are an important part of your lymphatic
1:24system as well as with the immune system
1:27in this diagram here you can see where
1:30all of the nodes are located throughout
1:32the body they're classified as small
1:35glandular structures and you can see
1:37them within the neck the axilla and the
1:40groin
1:41if you've gone to the doctors before and
1:43the doctor's gone underneath and feel
1:44they feel here right underneath your
1:47your throat what they're feeling for
1:49swollen lymph nodes if those lymph nodes
1:53are swollen it's actually a good thing
1:55because remember our body's first line
1:57of defense in protecting ourselves would
1:59be inflammation so we would expect to
2:02see inflammation here which is an
2:04accumulation of lymph and fighter cells
2:07also within the lymph nodules you'll see
2:09within the breast tissue they are masses
2:12of tissue that contain what's called
2:14microphages and lymphocytes lymphocytes
2:18are also a part of your immune system
2:21just like leukocytes these are cells
2:24that have a primary responsibility of
2:26aiding your body and removing any
2:29foreign pathogens you will see lymph
2:32nodules all throughout the body but
2:34especially within the spleen and in the
2:37tonsils another important component of
2:40the immune system or the lymphatic
2:42system would be the thymus and so the
2:45thymus as we've talked about before in
2:47the immune system what's produced we
2:50know that our body makes up what's
2:52called white blood cells one of the
2:54components in white blood cells is T
2:56cells T cells have a primary function to
2:59help in reading our body of pathogens
3:01and those T cells are made within the
3:04thymus
3:06interesting thing about the thymus is
3:08that it only grows and has a a purpose
3:12all the way up until adolescence once a
3:16child reaches the age of adolescence the
3:18responsibility or the work of the thymus
3:21starts to slow down until it becomes
3:23non-productive there is no more work for
3:26the thymus to do your immune system is
3:28developed at birth and it increases with
3:32you until you reach the age of
3:35adolescence now with that your body is
3:38producing T cells B cells remember B
3:41cells are those memory cells your body
3:44is developing those and it is developing
3:46your immunity the more your body becomes
3:49exposed to pathogens the better your
3:52body really is because those B cells
3:55those B memory receptor cells learn how
3:59to fight off pathogens when and if they
4:02invade the body
4:04so when the immune system becomes
4:06functional the thymus becomes almost
4:08non-existent because it has everything
4:10that it needs to protect you throughout
4:13the span of your life also within the
4:16lymphatic system is the spleen remember
4:18one of the largest organs within the
4:20lymphatic system or within the body
4:23period uh it is located in the upper
4:26left quadrant of the abdominal cavity
4:28and its primary responsibility is to
4:31filter blood
