hi i'm kathy and in this video playlist
i will be covering the
immune system if you are following along
with cards
i'm in the immune system section
of our medical surgical nursing edition
2.0 deck
and i will be following along with that
deck however you don't need to have this
deck to get value out of this
video series and i just encourage you if
you don't have our deck to make
flashcards of your own
because a lot of the information that
you need to know as a nurse
it takes repetition to really get that
information down
so some of the items that i'll be
covering in this playlist
include the difference between innate
and acquired immunity
we'll be covering immune system
malfunction
we'll be talking about different
disorders that relate to the immune
system
including lupus scleroderma
and hiv and then we will spend the
remaining time
talking about cancer we'll talk about
the risk factors
the signs and symptoms the diagnostics
for cancer
and treatment and we will definitely be
covering nursing care of patients who
have to undergo
chemotherapy radiation etc
in terms of the types of cancers that we
will cover we'll touch
on a number of different cancers but we
will focus more
on the most common types of cancer so
this includes skin lung prostate
breast and colorectal cancer so the
overall function
of the immune system is to protect the
body
from disease-causing microorganisms
and we do this through innate and
acquired
immunity innate immunity is something
that
everybody is born with these are
defense mechanisms that help protect the
body
by acting immediately against
all antigens okay so not a specific
antigen but
you know against all antigens so some
things that fall within
innate immunity include our inflammatory
response which i'll talk about more here
in just a minute
our skin so our skin is a barrier
to prevent harmful micro organisms from
entering our body
our stomach acid so if we were to
swallow some bacteria our stomach acid
will hopefully
um burn that up and cook that so it
can't hurt us
in addition we have mucus which helps to
trap pathogens so that i can't we can't
get
infected and phagocytic cells within the
body
these are all things that all people
have and work
immediately against all antigens then we
have
our acquired immunity this is where we
produce
antibodies against specific antigens
and we develop acquired immunity through
the action of b
and t cells and we'll definitely go into
more detail
about those cells and the action of
those cells
in my next video but before we get into
the details of acquired immunity let's
touch a little bit more
on the inflammatory response which is a
key part
of your innate immunity so inflammation
is your body's
protective reaction to injury disease
or damage to tissues in your body and
there are
three stages to inflammation the first
stage
we would expect warmth erythema
which is redness edema which is swelling
decreased function and or pain at the
site of injury
during the second stage white blood
cells
would kill off the microorganisms and
exudate
containing those white blood cells as
well as dead tissue cells
would accumulate at the site of inju of
the injury
and then during the third stage the
damaged tissue
will be replaced by scar tissue
okay so that is inflammation when i come
back with my next video we will go into
the details of acquired immunity thanks
so much for watching
