2. Let’s Review!

3. What are the roles of these
people in the community?

4. From the root word
“Circulate” which means
to pass from place to
place, our circulatory
system functions as the
transport system of our
body.

5. • The circulatory
system is
responsible for
distributing
nutrients, oxygen
and other essential
substances to all
parts of the body.

6. • It also removes and collects carbon
dioxide and other waste materials from
different parts of the body.
• It eliminates the
waste through
other organ
system of the body
which is the
Excretory system.

9. Heart-is a
hallow
muscular organ
located in the
chest between
lungs.

10. It is the pumping
organ of the
circulatory
system.

11. Your heart
is about the
size of your
clench fist

12. Pericardium- a
protective sac
encloses the
heart

13. a.Atria (atrium-
singular)- receives
blood to the heart
b. Ventricles- pump
out the blood from
the heart

14. Valves- prevents
the back flow of the
blood and ensure
that blood flows
only in one
direction.

15. How does blood delivers
from the different parts of
the body?

16. These are tubes that
serves as passageways
for the blood to reach the
different parts of the
body.
Blood
vessels

17. Types of blood vessels
2.a. Arteries- carry oxygen reach
blood away from the heart except
for the pulmonary artery.

18. Types of blood vessels
2.a. Arteries- carry oxygen reach
blood away from the heart except
for the pulmonary artery.
The pulmonary artery is the
only artery that carries oxygen-
poor blood to the lungs

19. 2.b. Veins- thin- walled and
floppy blood vessels. It carries
oxygen-poor blood from the
different parts of the body back
to the heart.

20. Capillaries- the
smallest blood
vessels

21. Aorta- the
largest blood
vessels

22. 2.b. Veins- thin- walled and
floppy blood vessels. It carries
oxygen-poor blood from the
different parts of the body back
to the heart.

23. Venules- the
smallest
veins
Vena Cava-
Largest veins

24. Dinuguan

25. 3. The blood- also known as
“River of Life”.

26. The blood delivers vital nutrients
and oxygen to all the cells in the
different parts of the body. It also
carries away waste products like
carbon dioxide and excess water for
excretion.

27. Components of Blood

28. After learning the how the
parts of your circulatory
system work, what can you say
about your body?
Are the parts of your
circulatory system working
well?

29. MIND GUESSING!
Group the class into 3. Each group will be
given an answer board. The group will
answer the questions through guessing the
words in jumbled letters. Whoever raised
their answer board with a correct answer
will be given points.
