1.Do you think your heart is the same as that of other animals?
2.How is your heart different from that of the other animals?
3.If you are to choose, which heart would you want to become and
why?

D. Discussing EXPLORE
new concepts Let the students label the different parts of the heart
and practicing Activity 2: The Human Heart
new skills #1 Objective: Identify the parts of the heart.
Materials: Activity sheet, pen
Procedure: Use the word bank below to label the detailed parts of
the heart. Write only the
letter of the corresponding part in the box.

WORD BANK
A. inferior vena cava B. right atrium C. pulmonary artery D.
aorta E. tricuspid valve F. pulmonary veins G. left atrium
H. left ventricle I. superior vena cava J. right ventricle

to Formative Activity 3: Pulmonary Circulation
Assessment The students will be group into three, they are going to answer
3) the activity and answer the guide question. Reporting will be
done after answering the activity.
Objective:
1.Trace the flow of blood through the heart.

Materials: Activity sheet and pen.

Procedure: Using the heart diagram, label the empty boxes with the
correct answers to show the coronary circulation of the blood.
G. Finding

concepts and
skills in daily
living

H. Making
generalization
s and
abstractions
about the
lesson

Guide questions:
1.How does the heart's four-chamber structure contribute to its efficient
pumping action, and what role do the atria and ventricles play in the
circulation of blood?

2.Could you outline the step-by-step process of how the heart pumps
blood, starting with the entry of oxygen-depleted blood from the body?

3.How does the heart's intricate system of valves and chambers work
together to ensure a unidirectional flow of blood, preventing backflow
and efficiently propelling oxygenated and deoxygenated blood to their
respective destinations?
EVALUATE
1. What part of the heart delivers unoxygenated blood to the lungs?
A. Pulmonary artery B. Pulmonary vein
C. Aorta D. Left Ventricle
2. True or False: The bicuspid valve is located on the left side of the
heart.
True False
3. The blood enters on the left side of the heart through the
______________ and enters the left atrium. It then passes through the
_____________to enter the left ventricle.
A. pulmonary vein, bicuspid valve B. pulmonary artery, mitral valve
I. Evaluating C. pulmonary vein, tricuspid valve D. pulmonary artery, aortic valve
learning 4. What part of the heart delivers richly oxygenated blood to the body?
A. Tricuspid Valve B. Superior Vena Cava
C. Aorta D. Pulmonary artery
5. True or False: Pulmonary veins take unoxygenated blood away from
the heart.
True False

EXTEND
 For this part of the lesson, you need to visit your barangay health
center and interview the barangay health officer about records of any
barangay constituents having problems with breathing or some
illnesses caused by malfunctioning of one part of the circulatory
system. Make a power point presentation or provide picture and short
description of the disease or illness.
Cite some cause/s of such illness/es. List also some tips to take good
care of your respiratory and circulatory systems.
