The circulatory system is responsible for transporting food, oxygen, carbon dioxide, and waste throughout the body via blood, which travels through arteries, veins, and capillaries. The heart, a muscular pump with four chambers, plays a crucial role in this process by pushing blood to and from the lungs and the rest of the body. Maintaining a healthy lifestyle is essential to prevent heart-related issues, such as heart attacks caused by blocked blood flow.

2. What is the
Circulatory System?
?
The Circulatory System
is how good and bad
materials travel through
our bodies.

3. The Circulatory System
moves food and oxygen to our cells.
The Circulatory System removes carbon
dioxide and waste
from our bodies.

which keeps us alive.

Under a microscope, blood
looks like cinnamon candy!
Food, Oxygen, Carbon Dioxide, and Waste is
carried throughout our bodies within a fluid
called BLOOD.

6. Blood travels through tubes called
blood vessels
http://www.besttreatments.co.uk/btuk/images/circluation_animation.gif
There are 3 types of
blood vessels:
•Arteries (red)
•Veins (blue)
•Capillaries

veins & arteries
looks something like this!
See all the red and white blood cells?

8. When we breathe in,
our lungs take
In OXYGEN.
The oxygen passes into
our blood through our
blood vessels.
Stille, Darlene R.,pg 16

9. BLOOD, with fresh oxygen
is pushed through our
blood vessels by a muscular
pump the size of our fist
known as the
HEART

11. Let’s take a look at the
Heart at work
See the difference in the HEART rate
when we are resting, in school, or
playing sports?

12. When we do not exercise or eat
properly, we damage our heart.

13. Fatty foods can make the inside of our
Blood vessels narrow
This blocks blood flow
If blood cannot reach the heart, the HEART muscle
begins to die
This causes a HEART ATTACK

14. Do You
REMEMBER
What Veins & Arteries
Are?
BLOOD VESSELS

15. VEINSare blood vessels that
carry used blood back to the heart.
The heart sends the blood
back to the lungs
to pick up
more oxygen.

16. The Aorta
http://www.mayoclinic.org/marfan/images/symptom2.jpg
The AORTA within the
heart is the largest ARTERY
The Aorta takes
blood with
oxygen and
delivers it to every
part of our body.
Arteries are blood vessels that carry
blood AWAY from the heart.
It’s a Fact! Your Bodypg 12

17. Capillaries
Are the smallest blood vessels
They branch off from every
Vein and Artery.

20. Blood travels through our bodies
Through BLOOD VESSELS
What are the 3 types of BLOOD VESSELS?
VEINS
ARTERIES
& CAPILLARIES

21. How many chambers does the
HEART have?
Right Atrium, Right Ventricle
Left Atrium & Left Ventricle

22. Which blood vessels carry
used blood BACK to the heart?
Which blood vessels carry blood AWAY from the heart to
other parts of our bodies?

23. What is the name of the LARGEST
ARTERY?
Hint: It is located within the HEART.

24. What can happen if we
do not eat HEALTHY
or EXERCISE?

25. Fatty Foods can block blood flow
If BLOOD cannot reach the HEART…
This can cause a
HEART ATTACK
YIKES!

Take Good care of your HEART!
Eat Healthy…
Exercise…
And get plenty of sleep!

Okay! Here’s a fact that will
AMAZE your friends…
“Did you know that if all your
ARTERIES, VEINS, & CAPILLARIES
Were joined together end to end
They would stretch more than
62,000 miles or 2 and a half times
Around the EARTH???!!!”
