YOUR
ORGANS
Brain
Your brain lives inside your skull and
the top of your spine. It controls
everything in your body – it is more
clever than any computer ever made.
It receives thousands of messages
telling it what is happening in the world
around you from your senses, as well
as sending thousands of messages to
your body telling it what to do.
Lungs
Sit very still and try not to move. What is the
one thing you always have to do, even when
you try to be as still as possible? Breathe! We
all need to breathe to stay alive. You have two
lungs and these make up one of the biggest
organs in the body. They sit underneath
your ribcage. If you place your hand flat on
your chest you can feel your lungs filling and
emptying with air as you breathe in and out.
The oxygen that this air brings into your lungs
is transported into your blood and pumped
around your body by your heart.
Intestines
You have two intestines – your small
intestine and your large intestine.
When food leaves your stomach it
goes to your small intestine first. This
is where the good parts of your food
(called nutrients) are absorbed into your
body and taken into your blood. Any
left over food moves into your large
intestine. Your large intestine deals with
everything your body does not need.
Here, water is removed from the food
and then what is left (your poo!) gets
ready to leave your body.
