This document contains materials for a lesson on how blood flows through the heart. It includes a title card that explains the complex flow of blood through the heart's four chambers, valves and blood vessels. It then lists activity cards, assessment cards and enrichment materials to help students understand and trace the flow of blood entering and leaving the heart. The main task is to trace the flow of blood as it enters the heart, with sub-tasks of identifying heart parts and naming blood vessels involved in circulation.

How Blood Flows Through the Heart
Tracing the flow of blood through the heart isn't as simple as it may
seem. The heart is a complex organ, using four chambers, four valves
and multiple blood vessels to provide blood to the body. The flow
through the heart is equally complex, with blood moving through the
heart, then the lungs, before returning again to the heart.
Blood returns to the heart from the body via two large blood vessels,
called the superior vena cava and the inferior vena cava. This blood
carries little oxygen, as it is returning from the body where oxygen is
used.
The blood first enters the right atrium. It then flows through the
tricuspid valve into the right ventricle. When the heart beats, the
ventricle pushes the blood through the pulmonic valve into the
pulmonic artery. This artery is unique: It is the only artery in the human
body that carries oxygen-poor blood.
The pulmonic artery carries blood to the lungs where it “picks up”
oxygen, and leaves the lungs and returns to the heart through the
pulmonic vein. The blood enters the left atrium, then descends through
the mitral valve into the left ventricle. The left ventricle then pumps
blood through the aortic valve, and into the aorta, the blood vessel that
leads to the rest of the body.
Without the valves the ventricles of the heart couldn’t develop any
force or pressure. It would be like pumping up a flat tire with a huge
hole in it. You could pump all you want, but the tire would never
inflate. In the case of the heart, blood would come into the chamber,
and just slosh through the chamber and out the valve at the bottom, or
upward in the wrong direction each time the ventricle tried to pump
blood.

5. Activity Card 1
Use SIM # 1 – NAME
RUSH
The mechanics is the
same with the game
“4Pics in a Word”. The
teacher will present
the pictures and ask
pupils to guess the
word out from the
picture shown
Is it fun?
No
Yes
The objective of the game is to let the
pupils identify the organs involve in the
flow of blood inside the heart and
through-out the body.

6. The objective of the game is to let the pupils identify
the organs involve in the flow of blood inside the
heart and through-out the body using four pictures as
hints.
This activity serves as the
starter of the lesson. It utilizes
images to motivate the learner to
continue to study the topic. It
develops the critical thinking
ability of the learner to connect
images to form the concept.
Name Rush is inspired by
the cellphone game application 4
Pix In A Word by which four
pictures will be shown to enable
the learner to guess the hidden
word.
This game also utilizes
images that are related to the
topic. Few letters will be shown
below the picture that will also be
the hint of the players to identify
the hidden concept.

Yes
The objective of the game is to let the

its parts. It also enable them to master the
parts of the heart

pictures according to
the parts of the hearts
will be pasted by the
pupils in the game

17. Activity Card 3
Use SIM # 3 – BLOOD
ATTACK
This is a board game
using dice. As the
players throw the
dice it corresponds to
the number of steps a
player may get until
he/she reaches the
aorta. The player
who reaches the
aorta will be declared
winner.
If it happen that a
player steps on the
BLOCKED tile he/she
must return to the
previous major part
of the heart. A
LADDER may allow
him/her to proceed
to the next tile.
The objective of the game is to follow the
flow of the blood towards the aorta for the
systemic circulation

All animals need to ________________ materials around to the different parts
of their body. This is the job of the ________________ system. The
circulatory system consists of a liquid called _______________, a pump called
the ________________ and a series of vessels called _________________
and ________________.
One thing that must be transported around is a gas called _____________.
Oxygen enters the blood through the ______________. It is then
____________ through the heart and around the body where it is used along
with food to make ______________. The body produces another gas called
_______________, which is a waste product. This gas is carried back to the
heart and then to the lungs where it is released back into the
_______________.
The vessels that transport blood _________ from the heart are called arteries.
The blood in arteries is _____________ red because it is rich in oxygen. The
vessels that transport blood _______________ the heart are called veins. The
blood in veins is ______________ red because it is low in oxygen.
________________ are small vessels that join the arteries and veins.
_______________ from food are also transported around the body by the
circulatory system. They enter the blood from the small _________________.
The circulatory system also helps to regulate temperature by transporting
_________________ around the body.

Investigating the Need for Carbon Dioxide in
Photosynthesis
Take a potted plant. Detach it. Insert one of
its leaves in a bottle containing potassium
hydroxide (KOH) solution as shown in the
figure. KOH absorbs all carbon dioxide in the
bottle. Leave the set up in sunlight for 48
hours. Test the leaf for starch.
