Your Guts
What do they do?
The Skeletal System




Provides a frame to
support and protect
body parts
Protects organs like
your brain
Marrow in your bones
makes blood cells
Without bones, you
couldn’t move!
The Muscular System


Works with your skeletal
system to help you move
Often work in pairs




Bend = flexor
Straighten = extensor
Resistance exercise
means more strength
Aerobic exercise means
heart strength and
muscle endurance
The Integumentary System




Skin, hair, and nails
protect other tissues
Keeps water in,
foreign particles out
(think band-aids)
Helps with sense of
touch
Regulates
temperature
The Cardiovascular System



Distributes blood to
other organs
Made of the heart,
blood vessels, and
blood
Blood carries oxygen


Oxygen poorlungs
Oxygen rich from
hearteverywhere
else
The Lymphatic System



Returns fluids to
blood vessels and
helps get rid of
bacteria and viruses
Takes fluid from
between cellsblood
The spleen and
tonsils are parts of
the lymphatic system
The Respiratory System



Brings in oxygen and
releases carbon
dioxide
Breathing involves
your lungs, muscles in
the rib cage, and your
diaphragm
Puts oxygen into your
blood; takes out
carbon dioxide from
blood and exhales it
The Digestive System



Breaks food down
into nutrients your
body can use
Breaking and
mashing food is
mechanical
Breaking large food
molecules into
simpler, useable ones
is chemical
The Urinary System



Removes waste from
your blood and
regulates body fluids
We need to get rid of
all the water we take
in
Kidneys filter our
blood
The Nervous System


Receives and sends
electrical signals
throughout the body
 Central: brain and
spinal cord
 Peripheral:
everything else
(nerves)
Regulates thinking,
sensing, feeling, movement,
heart rate, blood pressure,
body temperature, breathing,
balance, etc.
The Endocrine System

Sends out chemical
messages that control
other systems




Chemical messages are
called hormones
Hormones tell cells and
tissue what to do
Pancreas regulates blood
sugar
Includes adrenal and
thyroid glands
The Reproductive System


Female: produces
eggs,
nourishes/protects
fetus
Male: provides the
sperm for fertilizing
the egg
