A
So
I
just
want
to
review
with
you
the
blood
types
because
we're
going
to
be
doing
a
lab
where
we're
going
to
be
typing
some
different
blood
and
there's
a
lot
of
kind
of
confusing
words
with
this.
So
I
want
to
go
over
that
so
that
we're
clear
so
an
antigen
is
a
substance.
That's
found
on
the
cell
membrane
of
a
cell
that
can
trigger
a
response,
some
sort
of
an
immune
response.
So
if
your
body
does
not
recognize
that
antigen,
your
body
will
attack
it
to
try
to
protect
you
from
this
perceived
threat.
A
We
have
antigens
on
our
cell
membranes
that
we
recognize
they're,
not
a
threat
to
us,
and
so
we,
you
know
we
just
sort
of
leave
them
alone.
Blood
type
is
determined
by
the
presence
or
absence
of
these
antigens,
and
so
in
your
notes.
You
have
this
picture
here,
which
I
think
does
a
great
job
of
explaining
blood
typing
or
these
antigens.
So
if
you
have
a
blood,
you
have
a
antigens
on
the
surface
of
your
cell,
all
right
on
your
blood
cell
and
so
we're
going
to
just
call
them
circles
here.
A
If
you
have
B
blood,
you
have
these
little
blue
triangles
or
these
antigens
that
you
recognize.
If
you're
a
b
blood
person,
you
recognize
these
antigens,
they
are
not
a
threat
to
you.
If
you
have
a
b
blood,
you
have
both
a
antigens
and
B
antigens,
and
if
you
have
O
blood,
you
have
no
antigens
on
your
on
your
red
blood
cell.
A
So
let's
say
you
are
an
A
type
of
person,
a
blood
type
A
person
and
you
were
given
a
transfusion
and
you
received
a
b
blood.
Your
body
would
not
recognize
these
antigens
and
you
would
create
antibodies
that
would
attack
those
B
antigens.
So
these
anti-b
antibodies
are
basically
your
army.
Your
immune
system,
that
is
against
anti
against
these
B
antigens,
and
so
it
would
attack
it.
If
you
have
B
blood,
you
would
recognize
these
B
antigens.
A
But
if
you
were
given
an
a
transfusion
or
even
an
A
B
transfusion,
your
body
is
not
going
to
recognize
the
a
antigen,
and
so
your
body
would
attack
that
to
try
to
protect
you
from
this
perceived
threat.
If
you
have
a
b
blood,
you
recognize
the
a
antigen.
You
recognize.
The
B
antigen,
so
if
you
were
given
a
blood,
wouldn't
be
a
problem,
your
body
recognizes
those
a
antigens.
A
If
you
were
given
B
blood,
no
problem,
your
body
recognizes
those
B
antigens,
and
so
you
have
no
Army
to
attack
any
of
these
antigens
because
you
recognize
them
all
and
then
we
run
into
o
and
O
has
no
antigens
on
its
surface.
And
so,
if
you
are
an
O
person
and
you
received
a
b
blood,
your
body
doesn't
recognize
a
or
b,
and
so
it's
going
to
create
an
army
to
attack
those
and
because
you
are
O
blood
and
you
have
no
antigens.
A
You
can
donate
to
any
of
these
people
because
there's
nothing
on
the
surface
of
your
cell
to
be
perceived
as
a
threat.
Does
that
make
sense?
Okay?
So
what?
If?
Oh
so,
the
Rh
factor
so
like
if
you're
our
you
know,
O
negative
or
a
B
positive
or
whatever
those
things
are
the
a
the
positive
or
the
negative?
Is
this
Rh
factor?
And
it
is
the
presence
or
absence
of
another
antigen,
and
so
we
will
be
looking
when
we're
doing
this
lab.
A
We
will
be
looking
for
the
presence
or
absence
of
that
antigen
as
well,
and
so
what
happens?
If
we
are?
Let's
say
we
get
this
B
blood
say
we're
an
a
person
and
we
get
this
B
blood
with
these
B
antigens.
Our
body
does
not
recognize
that,
so
our
antibodies
will
attack
it
and
what's
happened.
What
happens?
Is
this
process
called
agglutination
and
it's
clumping
or
coagulation
of
the
blood,
and
then
we
will
have
hemolysis?
What
does
hemo
mean?
Blood
and
lysis
means
disintegration
right,
and
so
our
blood
would
Clump
together.
A
So
that
would
be
terrible.
If
that
happened
in
our
blood
vessels,
because
then
blood
wouldn't
be
able
to
move
past
it,
and
then
our
blood
would
disintegrate,
and
we
wouldn't
have
these
red
blood
cells
to
move
oxygen
throughout
our
body
and
to
give
to
our
cells,
and
that
would
be
terrible.
So
these
slides
these
Wells,
these
slides
that
we
have
are
what
we're
going
to
use
for
our
lab.
A
You
have
them
at
every
station,
and
so
if
gluten
agglutination
occurs,
it
is
because
there
was
an
antigen
that
was
perceived
and
it
was
attacked,
and
so
that's
what
agglutination
looks
like
so
in
this
slide
right
here
we
have
in
this
a
well.
We
have
agglutination
occurring
in
this
B.
Well,
we
have
agglutination
occurring
and
in
this
RH
well,
no
agglutination
occurred.
So
with
that
information,
what
type
of
blood
does
this
person
have?
Yes,
Danny
negative
and
what
type
of
a
b
negative?
So
a
is
present.
A
A
Washington
great,
and
so
we
are
going
to
figure
out.
We
are
the
CSI
investigator
and
we're
going
to
figure
out
the
blood
type
of
the
three
suspects.
We
have
blood
from
the
victim.
We
have
blood
from
the
crime
scene
and
we
have
blood
from
the
weapon
and
so
we're
going
to
test
all
of
those
and
see
if
we
can
determine
who
who
done
it,
who's
the
who's,
the
bad
guy,
so
we
will
be
determining
blood
types.
We
have
this
anti-a
serum.
So
like
this
little
this
little
station
right
here
we
have
a
blood
type.
A
This
is
the
crime
scene,
blood.
We
have
the
anti-a
serum.
So
if
we
put
this
blood
in
the
well-
and
we
put
this
serum-
that
is
against
a
in
with
there
and
in
with
the
blood-
and
it
does
agglutinate
well,
then
that
is
telling
us
that
a
is
present.
Okay,
we
have
anti-a
serum,
we
have
anti-b
serum
and
we
have
anti-rh
serum
if
it
does
Clump,
it
is
present.
A
A
No,
there
will
not.
If
we
put,
if,
if
the
sample
we
have
is
B
and
we
mix
it
with
anti-a
serum
will
it
Clump,
it
will
not
Clump
if
it
is,
if
we
mix
it
with
anti-b
serum,
will
it
Clump?
Yes,
it
will.
If
we
have
a
b
blood
and
we
mix
it
with
anti-a
serum,
will
it
Clump?
Yes,
it
will.
What
about
anti-b
serum?
Yes,
it
will.
What
about?
If
this
is
O
blood
and
we
mix
it
with
anti-a,
will
it
Clump?
No,
it
won't.
A
There
are
no
antigens
on
a
or
on
O
blood,
and
so
it
will
not
clump
what
if
we
mix
O
blood
with
anti-b,
it
will
not
Clump.
So
hopefully
this
will
help.
You
determine
the
blood
type.
So
it
says
here
that
you're
going
to
have
these.
We
have
these
slides.
Just
like
the
picture
before.
On
the
previous
slide,
we
have
a
b
and
Rh
Wells
I,
think
the
instructions
say
to
put
three
drops
of
blood
I'm,
not
that
particular
about
this.
That's
not
that
important
I
would
just
put
some
blood
in
there.
A
You
don't
want
to
fill
it
more
than
halfway.
I
also
have
white
paper
here.
Just
to
help
you
see
what
you're
looking
at
and
sometimes
the
paper
is
good
enough.
Sometimes
you
want
to
just
kind
of
slide
it
off
and
let
light
shine
through
it
so
that
you
can
see
if
there
is
clumping
or
agglutination
or
not.
So
what
you're
going
to
do
is
you're
just
going
to
put
some
drops
in
the
a
well
some
drops
of
blood
in
the
RH.
A
Well,
in
the
be
well,
and
then
you
will
take
the
anti-a
serum
and
put
it
in
the
a
well
and
so
I'm
just
going
to
put
a
few
drops
in
there
I'm
going
to
take
the
B
anti-b
serum,
put
it
in
the
B
well
and
then
I'm
going
to
take
the
RH
anti-rh
serum
put
it
in
the
RH
well,
and
then
it
should
happen
right
away.
Any
agglutination
and
so
I
see
my
results,
I'm
not
going
to
tell
them
to
you
and
then
on
the
back
of
your
lab
sheet.
A
You
would
just
write
the
results
and
you
can
write
whether
you
a
positive
or
A
negative
in
the
little
Wells
on
the
on
the
lab
sheet,
and
then
you
can
determine
the
type
of
blood
when
you
are
finished
with
this
slide,
you
can
just
dump
it
in
that
their
garbage
Beaker
and
then
wait
for
the
for
me
to
say,
rotate
we're
all
going
to
rotate
as
a
group
I'm
going
to
tell
you
right
now.
That
is
not
what
the
clumping
looks
like.
A
B
A
B
A
A
B
B
A
B
B
A
Is
anti-b
serum,
of
course,
okay,
of
course
it
is
all
right,
so
you
yeah
I,
find
it
very
helpful
to
lift
it
up,
and
so
you're
saying
this
is
not,
but
this
is
yeah
and
this
is
not.
Are
you
saying
that
is
that's
not
okay,
and
so
what
type
blood
type
is
this
be
negative,
B
negative?
This
is
the
only
thing
that's
present
yeah,
so
this
is
station.
Two,
so
I
would
do
negative
positive
negative,
be.
B
A
B
A
A
B
A
Think
so
too,
because
a
is
present,
B
is
not
a
or
RH
is
present
right,
and
so
then,
on
your
sheet
at
the
perfect.
That's
exactly
what
you
need
to
do!
Excellent
all
right.
So
it
seems,
like
everybody
understands
what
agglutination
looks
like
now.
Yes,
all
right
so
you're
going
to
rotate
to
the
next
station,
we're
going
to
do
this
in
a
clockwise
fashion
and
then
just
go
ahead
and
do
the
next
blood
sample.
B
B
A
B
A
B
B
A
A
A
A
A
B
A
A
A
B
A
A
B
A
A
And
this
is
your
last
station
correct.
So
when
you
are
finished
at
your
station,
you
can
just
go
back
to
your
seats
or
you
can
sit
with
your
partners
and
answer
the
questions
at
the
bottom
of
the
lab
and
then,
when
you're
finished
with
the
lab
sheet,
you
can
turn
it
in
in
this
basket.
That's
right
up
here
at
the
crime
scene,
sample.
