0:06did you know your body has its own
0:08version of a sewer system for removing
0:10unwanted toxins waste and excess water
0:13from the body
0:14this is called our lymphatic system
0:17like our blood circulation the lymphatic
0:19system is made up of millions of little
0:22vessels that branch all around our body
0:25but whereas arteries and veins carry
0:27blood the lymphatic vessels are much
0:30much finer and carry a colorless fluid
0:32called lymph our lymphatic system has
0:35three main duties
0:37one it contains white blood cells called
0:40lymphocytes which are used to fight
0:42infection
0:43two it acts as a one-way drainage system
0:46transporting fluid from body tissues
0:48into the blood circulation
0:50three it gets rid of waste products
0:52produced by cells
0:57as blood circulates the body plasma
0:59leaves the blood vessels and travels
1:01into the body tissues delivering food
1:04oxygen and hormones to the cells
1:07this plasma becomes tissue fluid and
1:09surrounds all our body's tissues it then
1:12collects waste products excess water and
1:14toxins from the cells ninety percent of
1:16this fluid passes back into the blood
1:18circulation however ten percent of the
1:21fluid is left behind and is known as
1:24lymph we therefore need a system to
1:26drain this lymph fluid
1:28so that we don't end up as a swollen
1:30fluid-filled balloon
1:31hence the lymphatic system the lymph
1:34fluid drains into lymph vessels where it
1:37then travels to lymph nodes which are
1:40found all around your body to stop
1:42backflow the lymph vessels have one-way
1:44valves and muscular walls that contract
1:47to force the lymph forward this is
1:49happening in millions of little
1:51lymphatic vessels in your body every
1:53minute of every day the lymph nodes
1:56filter the lymph destroying or trapping
1:58anything harmful the lymph nodes contain
2:01white blood cells called lymphocytes
2:03which attack and break down bacteria
2:05viruses damage cells or cancer cells
2:09this filtering and destroying is an
2:11important part of our immune system and
2:13stops nasty substances being fed back
2:16into our bloodstream which would make us
2:18sick the waste products and destroyed
2:20bacteria are then carried in the lymph
2:22fluid through larger lymph vessels up to
2:25your neck where the thoracic duct
2:27empties the lymph back into the blood
2:29circulation the bloodstream then removes
2:31the waste products from the body as it
2:33does with other waste
2:35as well as the lymph fluid our lymphatic
2:37system also includes a few organs the
2:40spleen
2:41thymus tonsils and adenoids they all
2:44have roles in helping our body fight off
2:47infections
2:48unfortunately like any sewer system
2:50things can go horribly wrong
2:52sometimes we get infections that cause
2:55the pumping to break down
2:57this can cause your arms or legs to
2:59swell to huge proportions
3:01sometimes the debris or other bad
3:03substances can make it past lymph nodes
3:06sometimes cancer cells do this and
3:08spread the cancer to other parts of the
3:10body which obviously isn't good for now
3:13we wish you all the best for your
3:14lymphatic health which you can help
3:17maintain by drinking lots of water and
3:19exercising
3:20keep on pumping if you liked the video
