MOST ESSENTIAL The Learners should be able to:
LEARNING Explain how the respiratory and circulatory systems work together
COMPETENCY to transport nutrients, gases, and other molecules to and from the
(MELC)
different parts of the body
I. LEARNING
OBJECTIVES
A. Content 1. how the different structures of the circulatory and respiratory
Standard systems work together to transport oxygen-rich blood and
nutrients to the different parts of the body
B. Performance The learners should be able to
Standard conduct an information dissemination activity on effective ways of
taking care of the respiratory and circulatory systems based on
data gathered from the school or local health workers
II. SUBJECT MATTER
a. Content Respiratory and Circulatory Systems Working with the other Organ
Systems
b. Materials Laptop, TV, Power point Slide
c. Reference a. MELCS Science pp. 391-392
b. Science 9 Learner’s Material pp. 9-11
d. Process Skills explaining, reasoning, analyzing
e. Values Be honest even if others are not and even others will not.

III. LEARNING TASK
Simple recall
ELICIT (5mins) What gas is necessary for life to exist?
What is the role of oxygen in the body?
Why do we need to inhale and exhale and not
inhale or exhale only?
ENGAGE (5mins) PROPEL
Oxygen is necessary for life to exist. Without it,
the cells in the body would not be able to release the
energy in food for power, and they would die within
minutes. When you inhale air, your respiratory system
gets oxygen. When you exhale, carbon dioxide is
released.
EXPLORE (20 mins) Activity 3. Just Go with the Flow!
Refer to Activity 3.
LM Science 9 pp
EXPLAIN (10 mins) Presentation/Reporting of output
ELABORATE How do the respiratory and circulatory systems work
(10 mins) together to carry out their common purpose?
PROPEL
Air first enters your lungs and then into the left
part of your heart. It is then driven by your heart into the
bloodstream, all the way through your body. The heart
pumps blood, which transports essential nutrients,
oxygen, and other chemicals to every cell in your body.
Once it reaches the cells, oxygen processes the nutrients
to release energy. Carbon dioxide is given off during this
process. The blood delivers carbon dioxide into the right
portion of your heart, from which it is pumped to the
lungs. Carbon dioxide leaves your body through the lungs
when you exhale.
B. Picture analysis:
What does the red and
blue colors indicate?
How do you compare
gas exchange in the
lungs and in the body
tissues?
EVALUATE (5 mins) Short quiz:
1. Air first enters your lungs and then into the
_______part of your heart.
A. Right C. Upper
B. Lower D. Left
2. Which of the following does not belong to the
group?
A. essential nutrients, C. oxygen
B. chemicals D. None of these
3. Which processes the nutrients to release energy
needed by the body?
A. Hydrogen C. Oxygen
B. Nitrogen D. Carbon dioxide
4. What gas is driven off when you exhale?
A. Oxygen C. Nitrogen
B. Carbon dioxide D. Hydrogen
5. Suppose you inhaled smoke from cigarettes would it
do good to your body?
I. No, because it is then released when you exhale.
II. Yes, because it will be transported throughout the
body tissues when dissolved in the blood
A. I only C. Both I and II
B. II only D. Neither I nor II

Activity 3
Just Go with the Flow!
Objectives:
Describe blood flow and gas exchange within the heart, circulatory system, and lungs
Explain the mechanism of how the respiratory and circulatory systems work together
Materials:
Paper strips Rope or ribbon
Marking pen Chalk
Procedure:
1. Perform the activity with your group mates (7-8 persons).
2. Assign and label different areas in the outdoor setting as: lungs, left atrium, left
ventricle, arteries, capillary, veins, right ventricle, and right atrium.
3. Using the marking pen, write down the word oxygen on as many paper strips as you can
and place them in the lung area. The capillary area should have papers with carbon dioxide
written on them.
4. Use the chalk to mark and define the different areas such as what is given in the diagram
below. Assign some members of your group to stand still on the different marked areas.
Figure 5. Illustration of the gas exchange activity
Choose two members from the group to take the trip around the different posts. Let the
partners start the tour in the lung area and together pick up a paper labeled as oxygen from
another member standing at his post. They should carry the strip of paper to the heart,
passing through the left atrium, and then to the left ventricle. As the partners go to every
station, they must leave a trail of rope or ribbon held by another member in a designated
area, until the path of the journey is completely traced.
6. Partners must run along the chalk marks representing the arteries into the capillary area.
7. Tell the partners to exchange the strip of paper representing oxygen for a piece of paper
representing carbon dioxide with a member in his designated area.
8. Make the partners run along the chalk marks representing the veins into the heart area,
first to the right ventricle, then to the right atrium.
9. The partners must then run back into the lung area where the process begins again.
When there are no more strips of paper, the activity is over. The leader may want to keep
placing new papers into designated areas to keep the game going on longer.
10. After the activity, record your observations and answer the guide questions.
Guide Questions:
Q9. How do the heart and the lungs work together?
Q10. What takes place when you inhale and exhale?
Q11. What does blood deliver to every part of the body?
Q12. Why is oxygen important to your body?
Q13. How will you describe the sequence of oxygen, carbon dioxide, and blood flow in your
own words?
