Transcript Inside my body - Communication4All

Have you ever looked in the mirror and
wondered what’s underneath your skin? It’s
your organs! Your skin, your heart, your
brain, your lungs and many other things are
all organs.
This picture
shows the main
organs of your
body. Let’s see
if you know
what they are
called.
brain
heart
liver
large intestine
Let’s have a look
at them in more
detail.
lungs
stomach
small intestine
skin
Your brain is about the size of a
small cauliflower. It sends
messages to the rest of your
body using the spinal cord. It is
a bit like your body’s own control
centre!
Your brain is protected
by your skull and is
surrounded by fluid to
cushion it if you fall
over.
Your brain needs oxygen from
blood to work properly. 3,500
pints of blood flow through
the brain every day!
The brain has two sides that control different
things in our body.
The right
side of
the brain
is the
creative
side.
The left
side of
the brain
is the
logical
side.
There are areas of the brain that help with all
of our senses, our behaviour, our speech, our
memory and our movements.
Your body needs
oxygen to stay
alive. When you
breathe in, oxygen
enters your lungs.
The oxygen goes
into your
bloodstream
through your lungs
and is carried to
the parts of the
body that need it.
Your lungs take up
most of the space in
your chest.
They are protected by
your ribcage.
Your left lung is
smaller than your
right lung so that
there is enough
space for your
heart.
Your lungs allow
you to take in
fresh air and
get rid of stale
air.
Your heart is like a pump but it is really a muscle.
It's located a little to the left of the middle of
your chest, and it's about the size of your fist.
The heart sends blood
around your body. The
blood provides your
body with the oxygen
and nutrients it needs.
The right side of
your heart receives
blood from the body
and pumps it to the
lungs.
The left side of the
heart does the
exact opposite: It
receives blood from
the lungs and pumps
it out to the body.
The liver is the
largest organ
inside your
body.
The liver helps the
body store energy
and gets rid of
toxins.
When you are fully grown
your liver will weigh 1.5
kilograms, but by the time
you are 60 years old it will
have shrunk to 0.8
kilograms! Don’t worry – it
will still do its job!
When you eat food passes
into your stomach and stays
there for two-and-a-half to
three hours.
Your stomach muscles
squash the food until it
is a creamy pulp.
Your stomach produces
juices to break down the
food and kill germs you
may have swallowed.
Your intestines are in
two parts.
The small
intestine
The large
intestine
Your small intestine is
a narrow coiled tube
that is about 6 or 7
metres long. When
food leaves your
stomach it comes here
so that nutrients can
be absorbed back into
the body.
Water and food that
cannot be digested pass
into your large intestine
and come out of your body
as waste.
Your skin is the
body’s biggest
organ!
Your skin is
very important.
It covers and
protects
everything
inside your
body.
Skin:
protects our bodies
helps keep our bodies at just
the right temperature
allows us to have the sense
of touch
The skin is tough and
strong, just right for
covering your body and
protecting it. Skin is always
renewing itself . Though
you can't see it happening,
every minute of the day we
lose about 30,000 to
40,000 dead skin cells off
the surface of our skin.
Our diagram looked showed only some of
the organs in our body. There are many
others, too many for us to look at now.
Let’s just look at a couple more that are
important.
Kidneys come in pairs.
If you've ever seen a
kidney bean, then you
have a pretty good
idea what the kidneys
look like. Each kidney
13 centimeters long
and about 8
centimeters wide about the size of a
computer mouse.
The kidneys are every bit
as important as the heart.
You need at least one
kidney to live!
One of the main jobs of the
kidneys is to filter the waste
out of the blood. Most of
the waste is just stuff your
body doesn't need because it
already has enough. The
waste has to go somewhere;
this is where the kidneys
come in. The waste that is
collected combines with
water (which is also filtered
out of the kidneys) to make
urine. This travels to the
bladder.
The
bladder
Drinking plenty of water and
avoiding rich food helps keep
your bladder and kidneys in
good condition.
The bladder is a
bag that collects
the urine that
leaves the
kidneys. When
your bladder is
about half full it
sends message
to your brain and
you go to the
toilet.
I hope you have enjoyed looking at some of
your body’s
organs. Let’s see how many you
brain
remember.
