The circulatory system transports blood containing oxygen and nutrients throughout the body using blood vessels and the heart. The circulatory system consists of blood, blood vessels, and the heart. Blood is made of plasma, red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and carbon dioxide, white blood cells protect against infection, and platelets form blood clots to stop bleeding. Arteries carry oxygenated blood from the heart while veins return deoxygenated blood to the heart. Capillaries connect arteries and veins to deliver blood to tissues. The heart is a hollow muscle with four chambers that pumps blood through the circulatory system around 60-100 times per minute, increasing during exercise to meet higher

1. THE CIRCULATORY SYSTEM

2. The circulatory system
carries/transports blood with oxygen
and nutrients to all parts of our body.

3. THE CIRCULATORY SYSTEM IS
MADE OF:
The blood
Blood vessels
The heart
Arteries
Veins
Capillaries

4. The blood is made up of four elements:
Plasma
Red blood cells
White blood cells
Platelets

5. PLASMA
It is a yellow liquid and all the blood
elements float on it.

6. Red blood cells

MAIN BLOOD CELLS

7. RED BLOOD
CELLS
They carry oxygen
and carbon dioxide
and give colour to
the blood.

8. WHITE BLOOD
CELLS
They protect us
from bacteria,
illnesses,
infections, etc.

9. PLATELETS
When there is an
injury in a blood
vessel, they close
that injury.

10. Platelets act like a gel
that makes a blood
clot.
Blood clot

12. They carry blood
containing oxygen
from the heart to the
rest of the body.
Arteries

13. Veins
They carry blood
containing carbon
dioxide from the rest
of the body to the
heart.

14. They are small
vessels that
connect arteries
and veins.
Capillaries

15. THE HEART

16. The
1. It is a hollow muscle that has four
chambers.

17. 2. It is like the engine of the circulatory
system because it pumps blood to the
rest of the body.

18. 3. It usually beats between 60 and 100 times
per minute but when we do exercise, it goes
faster.

19. … because our body needs to consume
more oxygen and energy, so the
circulatory system has to carry more
blood.
