Students will use chart to fill in the function & major
organs under each system column heading.
Skeletal System
Skeletal System
Function: Provides support for the body and
protection for internal organs
Major Organs/Structures:
Bones, cartilage, ligaments
(connect bone to bone), &
tendons (connect muscle
to bone)
Skeletal System
Interesting Facts:
• Blood cells are made in the
bone marrow inside your
bones.
• A bone cell is called an
osteocyte
Skeletal System
Interesting Facts
• Adults have 206 bones but as
infants, many of the bones are
cartilage
• The hands and feet contain
over half your bones in your
body
• Pound for pound, bones are
stronger than steel but tooth
enamel is stronger
• Bones only move because of
the muscles attached to them
Muscular System
Muscular System
Function: Allows and creates movement
Major Organs/Structures:
skeletal muscle, cardiac
muscle, and smooth
muscle
Muscular System
Interesting Facts:
• The muscles in the root of
your hairs give you
goosebumps
• The largest muscle is the
glueteus maximus
Muscular System
Interesting Facts:
• It takes 14 muscles to
smile and 42 muscles to
frown
• The longest muscle is the
sartorius
Respiratory System
Respiratory System
Function: Allows for gas exchange between
the external environment and the blood
Major Organs:
nose, pharynx,
trachea, larynx,
lungs
Respiratory System
Interesting Facts:
• The right lung is slightly
larger than the left
• The lungs are the only organ
that can float on water
• Pulmonary circulation refers
to the link between the
lungs and the heart—the
lungs supply the heart with
oxygenated blood
Integumentary System
Integumentary System
Function: The skin—protects the body from
damage.
Major
Organs/Structures:
skin, hair, nails,
sweat & oil glands
Integumentary
System
Interesting Facts:
• Skin weighs about 6 lbs. and sheds itself about every 27
days
• The majority of our skin has keratin which makes it
waterproof
• Melanoma is the most serious kind of skin cancer and is
fatal 35% of the time
Immune System
Immune System
Function: Protects the body from infection
Major
Organs/Structures:
white blood cells,
thymus, lymph
nodes, spleen
Immune
System
Interesting Facts:
• Sleep deprivation weakens the immune system
• Vitamin D produced by the skin increases the
effectiveness of the immune system so we get sick less
in Summer
• Allergies occur when your immune system treats
pollen as a foreign invader.
Endocrine System
Endocrine System
Function: Relays chemical information in the
body
Major
Organs/Structures:
pituitary gland,
thyroid,
hypothalamus,
adrenal glands,
pancreas, ovaries, &
testes
Endocrine System
Interesting Facts:
• Hormones are the
chemical signals
sent by the
endocrine system.
• Hippocrates was the
first person to
diagnose diabetes—
he did so by tasting
urine for sweetness
• Stress kicks the
endocrine system
into high gear
STRESS=HORMONAL
Excretory System
Excretory System
Function: Gets rid of wastes, toxins, and
excess water
Major
Organs/Structures:
kidneys, skin, urinary
bladder, ureters,
urethra
Excretory System
Interesting Facts:
• The bladder can
hold 24 oz. of urine
• The urea in urine is
a great fertilizer
• The skin plays a
role in the
excretory process
because it
produces sweat
Reproductive System
Reproductive System
Function: Creates the specialized cells needed
for reproduction
Major
Organs/Structures:
MALE: testes, penis,
epididymis, vas
deferens, urethra
FEMALE: ovaries,
fallopian tubes, uterus,
vagina
Reproductive System
Interesting Facts:
• The reproductive system
produces the body’s
smallest cells—sperm—
and largest cells--ova
• The vagina has something
in common with
tomatoes—they are both
acidic—this is essential so
that certain
microorganisms like
lactobacillis can live there
Circulatory
System
Circulatory System
Function: Allows for transport of gases,
nutrients, and wastes
Major
Organs/Structures:
heart, arteries, vessels,
and blood, urethra
Cardiovascular System
Interesting Facts:
• If you lined up all the veins,
arteries, and capillaries in
your body they would span
60,000 miles.
• The smallest vessels are
capillaries which are the
size of 10 human hairs and
the largest vessel is the
aorta which is the size of a
garden hose
Cardiovascular System
Squeeze the tennis ball 10 times.
The heart pumps with about as much strength it
takes to squeeze a tennis ball every time it
beats---about 100,000 times per day.
Heart Sounds
Listen to your heart beat through the stethoscope.
When the valves between the upper chambers (atria) and lower chambers
(ventricles) close, a "lub" sound is heard. When the valves in the pulmonary and
aortic arteries leaving the heart close, a "dub" sound is heard followed by a
longer pause.
The Heart’s Electrical System
In a particularly memorable scene in the 1984 film, "Indiana Jones and the Temple of
Doom," a man rips out another man's still-beating heart. While easily removing a person's
heart with your bare hand is the stuff of science fiction, the heart actually can still beat
after being removed from the body.
This eerie pulsing occurs because the heart generates its own electrical impulses, which
cause it to beat. As long as the heart continues to receive oxygen, it will keep going, even if
separated from the rest of the body.
Digestive System
Digestive System
Function: Breaks down and absorbs nutrients
Major
Organs/Structures:
Mouth, pharynx,
esophagus, stomach,
liver, small and large
intestines, rectum
Digestive System
Interesting Facts:
• The small intestine is about 22 feet
long, and about an inch in diameter.
(the length of the yarn)
• Cells along the inner wall of the
stomach secrete roughly 2 liters (0.5
gallons) of hydrochloric acid each
day, which helps kill bacteria and
aids in digestion. To protect itself
from the corrosive acid, the stomach
lining has a thick coating of mucus.
Nervous
System
Nervous System
Function: Relays information throughout the
body in the form of electrical signals
Major
Organs/Structures:
Brain, spinal cord,
peripheral nerves
Nervous System
Interesting Facts:
• If we lined up all the
neurons in our body, it
would be about 600 miles
long
• There are more nerve cells
in the human brain than
there are stars in the milky
way
Nervous System
A nerve cell is called a neuron.
