The document discusses the human circulatory system. It describes how the heart pumps blood through the body's network of blood vessels, delivering oxygen and nutrients to tissues and organs and removing carbon dioxide and waste. The circulatory system has about 5 liters of blood that continuously circulate through the heart, lungs, and all parts of the body in a double circulation of oxygenated and deoxygenated blood.

5. GROUP WORK
Trace the pathway of blood from the lungs
to the heart to every part of the body by
creating an illustration. Note the Oxygen
rich blood and Carbon dioxide rich blood
by indicating color.
Red- O2 rich blood; Blue-CO2 rich blood

8. GUIDE QUESTIONS.
a. How do the heart and the lungs work together?
b. What takes place in the alveoli when you inhale
and exhale?
c. What does blood deliver to every part of the
body?
d. Why is oxygen important to your body?
e. How will you describe the circulation of oxygen,
carbon dioxide, and blood in your body?

• PARTS AND FUNCTIONS
• HEART
• BLOOD VESSELS
• BLOOD
• CIRCULATION
• FROM THE LUNGS – TO THE HEART- TO OTHER ORGAN

11. CIRCULATORY
SYSTEM
is the main cooling

5 LITERS OF BLOOD
continuously traveling
through it by way of the
Circulatory System

22. •PULMONARY CIRCULATION
(lungs)
•CORONARY CIRCULATION
(heart)
•SYSTEMIC CIRCULATION
(the rest of the system’s processes).

23. The oxygen and CO2 are
exchanged…in the cells

HEMOGLOBIN in the
blood cells let go of
the cell’s oxygen
because of the large
CO2 (waste) count in
the tissue.

OCCURS

24. TRANSACT
The oxygen the
blood cells are
carrying is given
to the body’s
tissue. And the CO2 (waste) from the
tissue is given to the same blood
cell to be exhaled.

30. This organ is what pumps oxygen rich
blood, nutrients, hormones, and the other
things your body needs to maintain your
health, to your organs and tissues.
The pulmonary veins you see on the right
side of the diagram come from your lungs,
where the blood cells collect oxygen. It’s
then pumped out to the rest of the body
through the Aorta (Top).

31. All of the blue sections show blood cells
carrying waste, (C02) moving back to the
lungs (where the C02 will be replaced by
oxygen) through the Pulmonary Artery
(Top, blue)
Whenever the blood is pumped from one
section of the heart another a valve closes
behind it preventing the blood from moving
backwards.
