Circulatory System

The circulatory system uses your heart
and blood vessels to carry oxygen and
nutrients to parts of your body.
The Heart –part of the
circulatory system!
The heart’s job is to pump the blood throughout
the body.
 It is the strongest muscle in your body.
 It is about the size of your fist.
 Your heart pumps all the time and moves your
blood to clean and feed your cells.

Blood Vessels – part of the
circulatory system!



Blood vessels that carry oxygen away from the heart to
the body cells are called arteries. (RED)
Blood vessels that carry carbon dioxide in blood to the
heart are called veins. (BLUE)
Blood vessels that that let the fresh supplies leave the
blood and enter the body are called capillaries. They
connect the veins and arteries.

Skeletal System
A skeleton is the framework for your body and is
made of hard bones.
 There are 206 bones in your human body.
 Bones give your body its shape and protect your
organs.

your legs! Click on the back button to try

Sorry, the majority of your human bones
are not located in your skull!
 TRY AGAIN!
You are Correct!

Yes! We have many bones in our hands
and feet! You may go onto the next body

Muscular System




Muscles are made of many stretchy, elastic cells and
fibers that help make your body move.
There are more than 600 muscles in your body!
Muscles work in pairs. While one muscle is working the
other muscle is relaxing.
Muscles help keep your organs in place.
Do you think you should work
out with weights?

Click on what you think you should do.
 Yes, using heavy weights is healthy for my
muscles and my body.
 No, my muscles are not fully developed yet, and I
should wait until I am the right age to use heavy
weights.
Not Exactly

As a third grader, you need to be careful
to not lift heavy weights that could be
damaging to your body.

Nervous System
Your brain is the boss of your body! It runs the show
and controls just about everything you do!
 The brain is most important part of the nervous system.
The parts of the nervous system include the cerebrum,
cerebellum, brainstem, pituitary gland and
hypothalamus.
 Your brain can’t do it alone! It needs nerves and the
spinal cord. The spinal cord and nerves let messages
flow back and forth between the brain and body.

Quiz Time!

Why is the nervous system called the
“nervous system”? Click on the right
answer to go to the next body system!
– * A) because it is nervous
– * B) because it is shaky like you would be when your
nervous
– * C) because it involves nerves that are located
throughout your body.
Incorrect!

Our nervous system is not considered to
be nervous! Click on the back button and
try again!
Incorrect!

Our nervous system is not considered to
be nervous and shaky like if we were
nervous! Click on the back button and try
again!
You are Correct!

Everything you do depends on your
nerves involved in your nervous system.
Your brain sends messages to your nerves
to have you do something.
Digestive System


Digestion allows your body to get nutrients and energy
in needs from the food you eat.
The digestive process begins in your mouth while food
travels through your body. Your tongue plays a big part
in the beginning of the digestive process.

Quiz Time!

Where does the digestive system process
begin? Click on the correct answer to go
to the next body system!
• A) The mouth
• B) The stomach
• C) The diaphragm
You are Correct!

We begin the digestive process when we
put the food into our mouths! Click on the
arrow to go to the next body system!
Incorrect!

The stomach is part of the digestive
system, but it is not where it all begins!
Click on the back button to try again!
Incorrect!

The diaphragm is located near the
stomach but is not the first step in the
digestive system! Click on the back arrow
to try again!
Respiratory System
There are two large lungs in your chest. One is
a bit bigger than the other. The extra space
leaves room for your heart.
 The diaphragm works with your lungs to allow
you to inhale and exhale. Inhale is to breathe in
and exhale is to breathe out.


What do you blow out when you exhale?
*A) Oxygen
*B) Carbon Dioxide
*C) Saliva
Incorrect!

You actually inhale oxygen! Click on the
back arrow to try again!
Incorrect!

Your lungs do not exhale saliva! Spit may
be in your mouth and may come out, but
this is not what exhaling entails. Click on
the back button to try again!
Yes! You are right!

We exhale Carbon Dioxide. Our bodies do
not want carbon dioxide inside of us, so
we blow it out! Congratulations you have
