Paragraph
The
human
body
is
divided
into
many
different
parts
called
organs.
All
of
the
parts
are
controlled
by
an
organ
called
the
brain,
which
is
located
in
the
head.
The
brain
weighs
about
2.75
pounds,
and
has
a
whitish-pink
appearance.
The
brain
is
made
up
of
many
cells
and
is
the
control
centre
of
the
body.
The
brain
flashes
messages
out
to
all
the
other
parts
of
the
body.
The
messages
travel
in
very
fine
threads
called
nerves.
The
nerves
and
the
brain
make
up
a
system
somewhat
like
telephone
poles
carrying
wires
across
the
city.
This
is
called
the
nervous
system.
The
nerves
in
the
body
don't
just
send
messages
from
the
brain
to
the
organs,
but
also
send
messages
from
the
eyes,
ears,
skin
and
other
organs
back
to
your
brain.
Some
nerves
are
linked
directly
to
the
brain.
Others
have
to
reach
the
brain
through
a
sort
of
power
line
down
the
back,
called
the
spinal
cord.
The
brain
and
spinal
cord
make
up
the
central
nervous
system.
The
brain
doesn't
just
control
your
organs,
but
also
can
think
and
remember.
That
part
of
the
brain
is
called
the
mind.
Twenty-eight
bones
make
up
the
skull.
Eight
of
these
bones
are
interlocking
plates.
These
plates
form
the
cranium.
The
cranium
provides
maximum
protection
with
minimum
weight,
the
ideal
combination.
The
other
twenty
bones
make
up
the
face,
jaw
and
other
parts
of
the
skull.
Another
way
the
brain
keeps
it
self
safe
is
by
keeping
itself
in
liquid.
Nearly
one
fifth
of
the
blood
pumped
by
the
heart
is
sent
to
the
brain.
The
brain
then
sends
the
blood
through
an
intricate
network
of
blood
vessels
to
where
the
blood
is
needed.
Specialized
blood
vessels
called
choroid
plexuses
produce
a
protective
cerebrospinal
fluid.
This
fluid
is
what
