Common Cold Video Lecture - NEET

Oh gross
we're rolling okay hi I'm Ben with
today's question what is the common cold
when someone says I have a cold
what do they mean what they mean really
is that there's something in their body
causing a set of symptoms and we call
this set of symptoms the actual cold
this includes things like runny noses
sneezing coughing maybe even chills or a
monster of a headache it does not
include a fever
normally if there's a fever we call it
the flu and there are a lot of different
viruses that can cause cold symptoms but
about half the time the cold is caused
by a class of virus called
a rhinovirus like the words rhino and
virus put together but not not a
rhinoceros I would be way cooler the
rhinoceros excuse me Rhino virus gets
into the cell lining of your nose and it
starts reproducing it arrives from other
people so there are some myths we have
to bust one it is not cold weather that
causes a cold instead it's the fact that
cold weather causes people to congregate
together indoors and it makes it easier
for a rhinovirus to jump from one person
to the next
the virus generally moves from someone
else's hands to your hands through
something like touching a doorknob
putting your hands into your nose or
your eyes which I'm not going to do
because that would be kind of gross on
camera your body reacts to the presence
of the rhinovirus with its immune system
in the case of a cold the immune system
opens up blood vessels inside your nose
through inflammation and this also
increases your mucus and these two
processes give you that famous runny
nose and the stuffy fillings the
irritation caused by the virus and all
the fluid causes seizing the virus makes
it into the cell lining then your lungs
are going to start producing fluid and
mucus as well and that's what makes you
cough you're coughing up lung mucus as
the immune system gears up over seven
days and fights the virus back this
mucus thickens it gets grosser
this mucus thickens and it changes color
with dead cells a form of pus that is
true it is gross and it is totally true
but eventually the immune system
eliminates the virus completely and boom
you're well again you're hale and hearty
and ready for some more misadventure how
long does this take well a whole healing
process takes about seven to ten days if
you have average health so that's it
that's what people mean when they say
they have a cold we hope that you
