CONTENT
A. TOPIC:
The Learners demonstrate understanding of how the different
structures of the respiratory and circulatory systems work together
to transport oxygen-rich blood and nutrients to the different parts
of the body
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
Explain how the respiratory and circulatory systems work together
to transport nutrients, gases, and other molecules to and from the
different parts of the body
Infer how one’s lifestyle can affect the functioning of respiratory
and circulatory systems
a. Explain how circulatory and respiratory system works
together.
b. Differentiate the function of circulatory and respiratory
system in our body.
c. Appreciate the importance of circulatory and respiratory
system.

D. ENGAGE:
Let's Organize!
Using the given graphic organizer, fill in the missing parts,
description, and functions to complete the entire concept
E. EXPLORE
“PUMP IT”
Objectives:
Describe how the heart functions
Explain how blood is pumped by the heart
Materials: 1 beaker or wide mouthed jar
1 balloon
2 flexible drinking straws
1 pair of scissors
The students will group themselves
by counting. Those students who
are number 1 will be the group 1.
Same with 2-5 they will group
themselves according to the
number that they get.
After grouping themselves into 5
groups, the students will now have
a brainstorming and will perform
the activity.
Procedure:
1. Fill the jar half full of water.
2. Cut the neck of the balloon off at the part where it starts to
widen into a balloon. Set the neck part aside to be used later
on.
3. Stretch the balloon over the opening of the jar, pulling it
down as tightly as you can. The flatter you can get the surface
of the balloon, the better.
4. Carefully poke two holes in the surface of the balloon. Make
them about an inch apart from each other and near opposite
edges of the jar.
5. Stick the long part of a straw into each hole. The straws
should fit securely in the holes so no air can get through around
the straws.
6. Slide the uncut end of the balloon neck onto one of the
straws and tape it around the straw.
7. Set your pump in a large pan or the sink to catch the pumped
water. Bend the straws downward. Gently press in the center of
the stretched balloon and watch what happens to the water in
the jar.
8. Refer to the photo below to know what your setup must
look like.
Guide Questions:
1. What does the water inside the jar represent?
2. How will you compare the heart pump model and the
human heart?
3. How does the heart function as a pump?
4. Will the heart model be able to function properly if the
straw is blocked? Explain your answer.
F. EXPLAIN:
The leader of each group will share
For this activity, I prepared an infographic material
a summary of their discussion.
wherein you will use it as your guide in answering the
questions below.
Question:
1. Explain the parts and function of circulatory system.
2. Explain how the heart works.
3. Evaluate how the heart can be compared to a
mechanical pump
G. ELABORATE:
Proper Discussion:
The circulatory system is the life support structure that
nourishes your cells with nutrients from the food you eat and
oxygen from the air you breathe. It can be compared to a
complex arrangement of highways, avenues and lanes
connecting all the cells together into a neighborhood. The
circulatory system functions with other body systems to deliver
different materials in the body. It circulates vital elements such
as oxygen and nutrients. At the same time, it also transports
wastes away from the body.
Three major parts of the circulatory system, with their roles:
1. Heart – pumps the blood throughout the body.
Four chambers of the Heart:
The atria are the receiving chambers of the heart, accepting
blood from the body (right atrium) and from the lungs (left
atrium). The ventricles are the pumping chambers, moving
blood to the lungs (right ventricle) and into the body (left
ventricle)
2. Blood vessel – carries the blood throughout the body.
Arteries - carry oxygenated blood away from the heart to the
cells, tissues and organs of the body Veins - carry deoxygenated
blood to the heart Capillaries - the smallest blood vessels in the
body, connecting the smallest arteries to the smallest veins the
actual site where gases and nutrients are exchanged.
3. Blood – carries the materials throughout the body.
TYPE OF CIRCULATION
1. PULMONARY CIRCULATION- Movement of blood from
the heart to the lungs, and back to the heart.
2. CORONARY CIRCULATION- Movement of blood through the
tissues of the heart.
3. SYSTEMIC CIRCULATION- Movement of blood from the heart
to the rest of the body, excluding the lungs.
