4. Circulatory System Meaning
THE SYSTEM THAT CIRCULATES BLOOD AND LYMPH
THROUGHOUT THE BODY, CONSISTS OF
• HEART
• BLOOD
• BLOOD VESSELS

8. Steps in the System!!!!!!
• The Circulatory System pumps out blood from
the Heart to the Lungs to get Oxygen
• The heart sends oxygenated blood to the
arteries to send oxygen throughout the body
• Veins carry the de-oxygenated blood back to
the heart
• REPEAT!

12. Anatomy Parts
Right Atrium
1
Left Atrium
2
Right Ventricle
3
Left Ventricle
4
- receives blood low in oxygen from
the body and then empties the
blood into the right ventricle.
- receives blood full of oxygen
from the lungs and then empties
the blood into the left ventricle.
- pumps blood low in oxygen to the
lungs. In the lungs, the blood then
gets a "refill" of oxygen.
- pumps blood full of oxygen out to
the body.

14. Anatomy Parts
Pulmonary Valve
1
Tricuspid Valve
2
Aortic Valve
3
Mitral Valve
4
- is a heart valve that helps manage
blood flow in your heart.
- it helps blood flow in the correct
direction from the right atrium to
the right ventricle.
- it connects the left side of your
heart with your aorta.
- help prevent blood from flowing
backward as it moves through the
heart.

16. Circuits
Pulmonary Circuit
1
Systemic Circuit
2
Coronary Circuit
3
- carries blood without oxygen
from the heart to the lungs.
- blood with oxygen, nutrients and
hormones travels from the heart
to the rest of the body.
- provides the heart muscle with
oxygenated blood.

19. Blood Vessels Meaning
Blood vessels circulate blood throughout your
body. They help deliver oxygen to vital organs and
tissues, and also remove waste products. Blood
vessels include veins, arteries and capillaries.

20. Blood Vessels
1. ARTERIES
- are thin, muscular
tubes that carry
oxygenated blood away
from the heart and to
every part of your
body. The aorta is the
body’s largest artery.
2. VEINS
- these blood vessels
return oxygen-
depleted blood to the
heart. Veins start
small (venules) and get
larger as they
approach your heart.
Two central veins
deliver blood to your
heart.
3. CAPILLARIES
- these blood vessels
connect very small
arteries (arterioles)
and veins (venules).
Capillaries have thin
walls that allow
oxygen, carbon
dioxide, nutrients and
waste products to pass
into and out of cells.

22. Conclusion
Circulatory System is the system that contains the heart
and the blood vessels and moves blood throughout the body.
This system helps tissues get enough oxygen and nutrients,
and it helps them get rid of waste products. The lymph
system, which connects with the blood system, is often
considered part of the circulatory system.
