PARTS OF THE CIRCULATORY SYSTEM
1. Heart- It functions to pump
blood gathered from the veins
and into the arteries around the
body.

FUNCTIONS OF THE ORGANS
1. Our hearts work to pump deoxygenated blood from the veins through the
the lungs and into the arteries.
FUNCTIONS OF THE ORGANS
1. Our hearts work to pump deoxygenated blood from the veins through the
the lungs and into the arteries.
2. Our lungs gather that deoxygenated blood pumped from our veins. Our
lungs fill that blood with oxygen and gets rid of the excess carbon dioxide.
OUR BLOOD
Our blood is made of basic components; red blood
cells, white blood cells, platelets and plasma.

1. Red blood cells are cells that transport oxygen
and carbon dioxide to and from the tissues
around our body.

2. White blood cells are colorless cells that are a
part of our immune system, they protect our
body from unwanted microorganisms in our
bodies.

3. Platelets are the small, round cell fragments that
are found functioning in the clotting of blood,
basically these are the scabs we get when we trip
and scrape our knees or elbows.

THE PATH OUR BLOOD TAKES
Our blood travels through our body,
functioning to get our organs the oxygen and
nutrients it needs.
THE PATH OUR BLOOD TAKES
Our blood travels through our body,
functioning to get our organs the oxygen and
nutrients it needs.
Blood starts when it enters from the
right side of the heart through two veins, the
superior vena cava and the inferior vena
cava. Then it enters the right atrium, when
the right atrium contracts, the blood flows to
the tricuspid valve and into the right
ventricle. From the right ventricle, it goes
through the pulmonic valve, and to the
pulmonary artery, and towards the lungs.
From there it goes to the pulmonary veins
and to the left atrium, then through the
mitral valve, into the left ventricle, and
through the aortic valve. Finally, it reaches
the aorta, and from here it circulates around
the rest of the body.
HOW IT WORKS WITH OTHER SYSTEMS
1. (Respiratory System) The circulatory system gathers the oxygenated blood
from the lungs and into the blood stream where it travels to different parts
of your body to be exchanged for waste materials.

2.
(Digestive System) The circulatory system gets the nutrients broken down
by the digestive system and delivers it to cells and blood vessels.

3.
(Muscular System) All of the blood vessels in the circulatory system are
made up of smooth muscle, and the heart is also a muscle called the cardiac
muscle.
All cells need blood to
transport oxygen for respiration.
Without oxygen, the brain would
eventually die. A human can
survive without a digestive system,
for nutrients can be taken in for
your body IV drip. You can also
survive without a nervous system.
A person can still live, but they
would not be able to move, feel,
touch, etc.
1. If you laid out all the veins,
arteries, and capillaries, they
would wrap around the Earth 2.5
times?
2. A heart can still beat after being
removed from a body?
3. A condition called “broken heart
syndrome” can temporarily
weaken the muscle of the heart? It
is often confused for a heartbreak.
Basically, someone can break your
heart.
4. After 120 days, a red blood cell
will die from aging or damage.
