Circulation
- The circulatory System
- Carries nutrients and oxygen to cells
- Removes Carbon dioxide from the cells
- transports other waste products to where they can be disposed of
- distributes heat around body
- heart
- Engine room of circulatory
system, pumps continuously
to keep the blood moving
through vessels

- blood vessels
- Motorways, main roads and side streets along which blood flows

- blood
- Carries nutrients and oxygen to cells
- Blood vessels
- Arteries
- carry blood away from the heart
- when the heart beats, it
pumps blood through
arteries under pressure
- the walls of the arteries must be
tough and elastic to withstand
this pressure
- the walls of the arteries must be
tough and elastic to withstand
this pressure
- If an artery is cut, then high
pressure within it causes blood to
spurt out very quickly
- Arteries are protected deep in your body
- Arteries are protected deep in your body
- carry blood away from the heart
- capillaries
- extend through the body,
arteries branch into
smaller and smaller blood
vessels. The finest of these
are capillaries
- Capillaries walls are only one cell
thick, this allows dissolved
material to pass through them
- extend through the body,
arteries branch into
smaller and smaller blood
vessels. The finest of these
are capillaries
- veins
- Veins carry blood
back to the heart
- Blood is pushed back to the heart
by the contractiion of muscles
pushiing against the veins
- To make sure blood moves in one
direction, there are valves along the
veins
- Valves open when blood is
flowing to the heart and
close when blood is flowing
away from it
- Valves open when blood is
flowing to the heart and
close when blood is flowing
away from it
- Veins carry blood
back to the heart
- Arteries
- Bruises
- Bruises form when capillaries
near the skin burst and the
blood leaks into the surrounding
tissue

- Heart
- It is the size of
your fist and
situated in the
middle of your
chest
- The circulatory system is
known as a double system
because there are two
separate circuits
- In the first circuit: Flood flows from the heart
to the body and back to the heart, this circuit
carries oxygen and nutrients to the heart
- In the second circuit, blood
flows from the heart to the
lungs and back again
- In the first circuit: Flood flows from the heart
to the body and back to the heart, this circuit
carries oxygen and nutrients to the heart

- Blood
- The only organ in the
body that exists as a

- In blood, there are red
