THE CIRCULATORY
SYSTEM
By Bianca and Charlee
What is the job of the circulatory
system?
• The circulatory systems job is to transport
materials such as nutrients, oxygen, water
and billions of blood cells. It also takes
away carbon dioxide that your body cells
produce.
• The circulatory that holds the heart pumps
a fair amount around your body.
BLOOD!!!!!!!
• Red blood cells carry
things like carbon
dioxide and oxygen.
Red Blood cells are
very important on
blood duty one drop
of blood carries in it
millions of blood cells.
• When a disqusting
germ or horrible
infection enters the
body the white blood
cells go over to see is
what is happining.
White blood cells
keep their eyes out
for diseases.
Blood cells!!!!
• There are two types of blood cells in your body one is
called white blood cells the other is called red blood
cells. Red blood cells are the ones that are formed from
bone marrow and are important for the protein
Haemoglobin, which carries oxygen
White blood cells are made up of platelets carry out the
function of warding off infections and blood clotting.
Blood cells is the medium the body requires to fill with
vitamins and "good bits" to then carry to all parts of your
body, like oxygen, nutrients and defence mechanisms to
help the body fight off bacteria and diseases.
The Heart!!!!!!!!

The left side of your heart sends that oxygen-rich blood out to the body.
The body takes the oxygen out of the blood and uses it in your body's
cells. When the cells use the oxygen, they make carbon dioxide and other
stuff that gets carried away by the blood. It's like the blood delivers
lunch to the cells and then has to pick up the trash!
The white blood cells have a rather short life cycle, living from a few
days to a few weeks. A drop of blood can contain anywhere from 7,000
to 25,000 white blood cells at a time. If an invading infection fights
back and persists, that number will significantly increase.
A consistently high number of white blood cells is a symptom of
Leukemia, a cancer of the blood. A Leukemia patient may have as many
as 50,000 white blood cells in a single drop of blood.
Important organs in your body!!!
• The heart is one of the most important organs
in your body because it has the job of
pumping blood all around the body. the heart
is protected by your rib cage. Your heart is
placed slightly to the left side of your body.
Your heart weight is around about half a kilo
the heart is a little lighter in the female by
about a few grams. your heart is about the
size of your fist.
The heart parts
• The circulatory is made up of three main
components the heart , the blood vessels and the
blood The heart is the pump, the vessels are the tubes
that carry the blood around the body, and the blood
is the circulating fluid. The main job for the
circulatory system is to keep us alive and to pump
the blood around our body. The circulatory system
carries food or oxygen to all the different blood
cells, in response the circulatory system takes away
all the things that are bad for us such as carbon
dioxide and other things like bacteria
