When you eat food it goes
through your digestive
system.
ALONG THE WAY, YOUR BODY TAKES
NUTRIENTS FROM THE FOOD YOU EAT
AND GETS RID OF THE FOOD IT CAN’T
USE.
What gives humans energy to
work and play?
FOOD=ENERGY
How about…
Cars?
Light?
Why do we
need it?
Functions
1.
Breaks downs food into smaller
pieces
2.
Transports food/nutrients into the
body to provide energy
3.
Eliminates waste

Parts
Digestive Track: Where
food passes through
• Mouth: teeth, saliva
• Esophagus
• Stomach
• Small intestine
• Large intestine
• Rectum
What happens when you smell or see your
favorite food?
What happens when you eat too fast?
Muscles help squeeze food down
your esophagus!
Digestion
Stomach
• Stretches when full
• Food stays about 3 hrs.
• Stores and blends food
with digestive juices
• Acid Kills bacteria
Small Intestine
• Food & nutrients are absorbed into
blood
• 20 feet long (narrow)
• Most digestion occurs
Digestion
Large Intestine
• A.k.a- Colon
• 5 feet long
• Forms and stores feces
• Stays for 2 days
Rectum
• Expels waste

Circulatory System
Purpose:

To circulate blood
throughout the body

To carry oxygen to the
organs and other
areas of the body that
need it

Distribute nutrients
Circulatory System
It is made up of 3 main parts:
1) The Heart
2) The Blood
3) The Blood Vessels
-Capillaries
-Arties
-Veins
This system is also known as the cardiovascular
system
Cardio=heart Vascular=blood vessels
The Heart
• Is really a muscle
• Located to the left of the middle of
your chest
• The size of your fist
What does it do?
The heart sends blood around your
body. The blood provides your body
with the oxygen and nutrients it needs.

Circulatory
System

Parts of the Heart
Valve
How it Works
Your heart is sort of like a pump, or two pumps in one.
The right side of
your heart
receives
oxygen-poor
blood from the
body and
pumps it to the
lungs.
The left side of
the heart does
the exact
opposite: It
receives
oxygen-rich
blood from the
lungs and
pumps it out to
the body.
Blood Vessels
•Carry blood and nutrients to various parts
of your body
 Arteries = away from heart (oxygen)
 Veins = towards the heart (no oxygen)
 Capillaries = Connect arties and veins

Vocabulary

Valves-Doors that open and close for blood to flow through.

Blood vessels- Tubes that blood flows through

Arteries-Blood vessels that carry blood AWAY from the heart

Veins-Blood vessels that carry blood towards your heart
Blood
1.
Red Blood Cells-Carry oxygen through body (most)
2.
White Blood Cells- Fights infections and makes antibodies (body makes
more when sick)
3.
Platelets- Helps your blood clot (stops bleeding) and are very sticky
4.
Plasma- Yellowish liquid that carries nutrients throughout the body (from
food) and gives you energy
Blood Types
1.
A
2.
B
3.
O: Most common (46% of population)
4.
AB: Most Rare (fewer than 10%)
Activity…
 Vessels
are like hoses. If you bend a
hose, the stream of water slows down. If
you straighten it out, the water flows
again.
 The same thing happens to your blood
vessels…
 Squeeze
your wrist for 30 seconds
 Feel the tingling?
 That is a message to your brain that cells
aren’t getting enough oxygen.

clogged

#1 cause of death in America and it can be prevented!
Symptoms
• Shortness of breath
•Chest pain
•Irregular heart beats
•Faster heartbeats
•Weakness/dizziness

Stroke

Occurs when blood flow to an area in the
brain is cut off.

The brain get deprived of oxygen.
• If a stroke is not
caught early,
permanent brain
damage or death
can result.
Stroke Symptoms
• Weakness in face, arms, or leg one side of
the body
•Loss of speech/difficulty talking

Respiratory System
Purpose:
Breathing
Parts of the Respiratory
System
 Nose
 Trachea
(wind pipe)
 Bronchial Tubes
 Lungs
 Bronchioles (smaller
tubes)
 Alveoli (tiny air
sacs)
 Diaphragm
tubes
al
The LUNGS allow oxygen to be
taken (inhale) into the body.
When you exhale the body
gets rid of carbon dioxide.
Bronchioles are
small airways in
the lungs
Alveoli are tiny air sacs
where oxygen is
exchanged for carbon
dioxide
Take a Journey
The NOSE
breathes in air and take out air.
Windpipe
The TRACHEA is a tube
that allows the passage
of air.
The Diaphragm is a muscle
that contracts and relaxes
to let air in and out of the
lungs
Activity…
The passageway of air
Respiratory Diseases
Emphysema
Damage to the air sacs in the
lungs, making breathing very
difficult.
