Throughout this PowerPoint there will
be songs via audio file links:
These are hyperlinked to a CD called,

to copyright issues, you will need to
have a copy of the CD inserted into
your hard drive.
Gwinnett County Teachers: You may borrow
this CD from the Adapted Curriculum Lab.
Science Standards:
S7L2 - Students will describe the structure and function of cells, tissues, organs, and organ systems.
e. Explain the purpose of the major organ systems in the human body (i.e., digestion, respiration, reproduction,
circulation, excretion, movement (muscular), control, and coordination, and for protection from disease).
ELA Standard:
ELAGSE.7.W.2 - Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information
through the selection, organization, and analysis of relevant content.
a. Introduce a topic clearly, previewing what is to follow; organize ideas, concepts, and information, using
strategies such as definition, classification, comparison/contrast, and cause/effect; include formatting
(e.g., headings), graphics (e.g., charts, tables), and multimedia when useful to aiding comprehension.
Digestive System
Main Organs
Mouth, Esophagus,
Stomach
Function
Break down food
to make energy
for the body (eating).
Mouth
Esophagus
Stomach
Digestive System
Fun Facts:
Your stomach,
is a stretchy sack
shaped like the letter J.
You get a
new stomach lining
every 3-4 days
J
Respiratory System
Main Organs
Nose and lungs
Nose
Lungs
Function
Take in (inhale)
oxygen and let out
(exhale) carbon
dioxide to breathe
Respiratory System
Fun Fact:
You take more than 20,000
breaths when just sitting
during a 24 hour day.
Young children laugh
an average of 300 times
a day; adults average
only 15-100 times a day.
Circulatory System
Main Organs
Heart and
Blood Vessels
Function
Heart pumps blood
through the body
Blood vessels move
oxygen and nutrients
throughout the body
Heart
Blood
Vessels
Circulatory System
Fun Facts:
It takes only 20 seconds
for blood to circulate
(travel) through
the entire body!
The heart makes enough
energy each day to drive
a truck 20 miles!
Skeletal System
Main Organ
Bones
throughout
whole body
Function
Gives the body
its shape
Bones
Skeletal System
Fun Facts:
At birth, babies have
300-350 bones, some of
which fuse (join) together.
An adult human has
206 bones.

Muscular System
Main Organs
Muscles
throughout
whole body
Function
Help
the body move
muscles
Muscular System
Skeletal Muscles
You make them move
(Legs, neck, hands, etc.)
Hand muscles
Involuntary Muscles
They move by themselves
(muscles to breathe;
muscles to move blood, etc.)
Lung muscles
Cardiac Muscle
Only found in the heart
(helps heart beat)
Cardiac Muscle
Muscular System
Fun Facts:
The most flexible
muscle is the tongue,
which can take many
shapes and is always
moving, even in sleep
Human body has more
than 600 muscles
