Introduction
Hello, and welcome to The Super Circulatory System! In
this slideshow you will learn many facts about The Super
Circulatory System! We hope you enjoy this presentation!
The Heart
By Lauren Groff
The Heart
• Your heart beats more than thirty million times in one year.
• Did you know that it is a hollow muscular organ?
• It is tilted slightly to the left and only weighs around ten
ounces.
• You know this, but it is NOT an actual heart shape.
• Your heart muscles squeeze together and push blood around
your body through tubes called blood vessels every 60-100
times every minute!
• Did you know that your heart is divided into two sides?
Each side has an atrium and a blood from lungs ventricle.
Blood enters the two atria and is pumped or squeezed into
the ventricles.
• The right side of your heart fills with used blood from
your body. The left side fills with blood from the lungs.
Then it is pumped into two big blood vessels and out of
the heart.
• Your heart beats 90 times in one minute.
What Do Cells Do?
By: Sean O’ Connor
There are two different color cells which are the red
and white cells. Red Blood cells carry oxygen from the
lungs to all the cells of the body. White blood cells are like
soldiers protecting the body.
We each have about twenty five trillion red blood cells,
hundreds of times more blood cells than there are stars in
the milky way galaxy. Every second our body's make about
three million red blood cells, and in that same second about
an equal number die. Each red blood cell lives no longer
than four months.

What Color Veins Are In
The Body?
What are veins? Veins are vessels that carry blood
back to the to the heart. Your blood travels around your
body like a fast flowing river. The blood flowing through
your body as known as your bloodstream. It carries the
supplies your body needs to grow and stay healthy. The
purified blood goes back into your bloodstream to continue
its journey around your body.
Your blood passes from capillaries' into the smallest
branches of your body. Veins are similar to arteries, and two
often lie next to each other. But veins are closer to the
surface of the skin. Veins also have narrower, thinner walls
than arteries with only a very thin layer of muscles. The
blood in your veins has less oxygen in it then the blood in
your arteries. This makes it dull purple- red. Normally, three
fifths of your blood is in your veins.
What Are Arteries
By: Kevin Moran
Your blood travels around your body through a number of
tubes called blood vessels, also known as arteries. Arteries
are the opposite from veins. They carry blood away from
the heart. The largest artery in the human body is the Aorta.
It has thick elastic walls to move blood along through your
smaller arteries. And your smallest arteries are called
capillaries. Your arteries split into smaller and smaller tubes
to reach every part of the body.
What Keeps The System
Healthy?
The things that keep the circulatory system healthy are…
*Vegetables
*Fruits
*Meat
*Water
* And other things healthy for the heart!
What Does The System Do
For The Body?
The Circulatory System does many things for the body. It
helps circulate blood through the body.
What Are The Parts
The parts that make this amazing system up is the veins,
arteries, heart, cells, ventricles, and atria( Which help the
heart,). These parts all work together to make up this
system.
How Does The System
Work?
Every time the heart beats it pumps blood through the body.
The blood travels through the veins and the arteries.
What Might Cause The
System Not To Work?
Some things that might affect the system is the...
*Heart attacks
*Lung cancer or any kind of cancer.
*Blood Clogs.
*Fats and not enough exercise.
What Would Happen
Without The System?
Without the system we would not have blood to
circulate throughout the body. Without blood it would not
reach the body parts for example the lungs. The lungs
would not be able to work which means they can not
oxygen to inflate and we would not be able to breathe.
