bones protect our organs heart, lungs, etc. All
of those bones hold up your whole entire
body! If you didn’t have bones, you would flop
around like a jelly fish. When you break bones,
It takes a long time to heal. Try not to break
bones. Your skeleton is very important.

epidermis, the dermis, and the
subcutaneous layer. The epidermis
Is translucent and has no blood
vessels. The dermis nourishes the
epidermis and contains hair glands.
it also holds sweat glands and
blood vessels. The subcutaneous
layer is an energy reserve for the
body and it stores fat.
8. The Nervous System
• The nervous system connects
the brain to the spinal
cord. This takes messages
from your brain to all of
the rest of your body and
tells them when to move.
Neurons send signals to
other cells, that is how
they know how to move.
Neurons travel along axons.

The nervous system is made up of your brain, spinal cord, and a network of
nerves that go through your whole entire body. It controls your body.
Neurons carry messages to and from different parts of your body using a
type of electricity! Neurons are shaped like flat stars!
Healthy Hints!!!!! To calm your nerves, take a deep breath!
10. The Digestive System
• Your digestive system is an essential part to every day life.

11. The Digestive System (Part 2)
Your digestive system is made
up of the digestive tract. The
digestive tract is a series of
hollow organs. These organs
are joined to a hollow tube
that goes from the mouth to
the anus. The organs that
make up the digestive tract
are the mouth, esophagus,
stomach, and the small
intestine. The digestive tract
has a layer of smooth muscle
that helps break down food.

12. The Circulatory System

pg
You can’t live without your circulatory system. It pumps
blood through your body and that is very needed. Your
heart is behind all of that pumping. There are arteries
and veins that go to your body from your heart and
from your heart to your body. The arteries carry blood
with oxygen and the veins carry blood without oxygen.
You wouldn’t be alive without your circulatory system.
Healthy Hints!!!!!!!
If you eat junk food, your
arteries will get blocked and
you could have a stroke.
13. The Circulatory System (Part 2)
• Your circulatory system is made up of
blood vessels and the muscles that
help control the blood flow around
your body. The main parts of it are
heart, veins, capillaries, and arteries.
The blood leaves the heart and goes to
the aorta. When the blood leaves the
aorta, it is full of oxygen. The oxygen
blood travels through your body. When
it comes back to the heart, it drops off
carbon dioxide and picks up oxygen
from your lungs.

14. The Respiratory System
• Your respiratory system is how you breathe! When
you breathe in air through your mouth or nose it
goes to your lungs and puts oxygen in your blood.
Your blood needs oxygen, as you read in “The
Circulatory System”. Your life would be very bad if
you didn’t have your respiratory system.
http://library.thinkquest.org/5777/resp1.htm
15. The Respiratory System (Part2)
• We breathe to get rid of carbon dioxide and to
take in oxygen. The oxygen goes to your blood
cells. The respiratory system includes airways,
lungs, and respiratory muscles. Without your
respiratory system, you wouldn’t be able to
talk! http://kidshealth.org/kid/cancer_center/HTB
• Healthy Hints!!!!! Don’t put anything in or
near your mouth that is not food because you
could inhale it and choke.
16. The Heart
• Your heart is very
important. It keeps the
blood pumping through
your body. It sends blood
without oxygen to your
lungs and blood with
oxygen to the rest of your
heart.
• Healthy Hints!!!!!! Keep
active so you don’t have a
heart attack.
17. The Heart (Part2)
• Your heart is a muscle that pumps blood
through your body using steady contractions.
If it is healthy, it will beat approximately 72
times per minute. The main parts of your
heart are the left ventricle, right ventricle, left
atrium, right atrium, and the pulmonary
artery.
