What is Lymphatic System? Video Lecture - Class 10

did you know your body has its own
version of a sewer system a good system
for handling excess water and debris is
an important part of any community it
helps take away contaminated substances
it might harm us engineers have designed
great systems of pumps and pipes to help
our sewage systems do these important
jobs most of the time we barely notice
these systems unless they fail to work
bu it turns out your body has a similar
system for dealing with excess water and
contaminated substances there are
millions of tiny vessels in your body
whose job it is to gather excess water
proteins cells in various bits of debris
this is called the lymphatic system the
water which is leaked out of your blood
vessels is returned to the blood stream
in your shoulder so you don't blow up
like a big water balloon the pumping
happens because each little lymphatic
vessel has valves at each end they keep
the fluid moving in the right direction
the vessel squeezes to keep the fluid
moving along this is happening in
millions of little lymphatic vessels in
your body every minute of every day as
this water is pumped back up to your
shoulder has to be cleaned so that the
bits of debris in the water stream say
if you get a cut don't get into your
bloodstream and make you sick the
lymphatic system pumps all that water
through at least one lymph node these
are like tiny water treatment plants
where specialized immune cells recognize
and destroy the foreign debris voila all
clean and ready to go back into the
bloodstream unfortunately like any sewer
system things can go horribly wrong
sometimes we get infections that cause
the pumping to break down this can cause
your arms or legs to swell to huge
proportions that's a disease called
lymphedema and it is no laughing matter
sometimes the debris or other bad
substances can make it pass lymph nodes
sometimes cancer cells do this and
spread the cancer to other parts of the
body bad news for now we wish you all
the best for your lymphatic health which
you can help maintain by drinking lots
of water and exercising keep on pumping
