Circulatory & Respiratory
System
Anticipatory Set
Prepare whiteboards and materials.
When I say, “go,” you will count how many times you
feel your pulse.
When I say, “stop,” you will write down the # of pulses
you felt.
Multiply the # of pulses by 15.
This is the approximate # of times your heart contracts
each minute!
Put away whiteboards and materials.
Standard
Life Science
2a. Students know many multicellular organisms have
specialized structures to support the transport of
materials.
2b. Students know how blood circulates through the heart
chambers, lungs, and body and how carbon dioxide
(CO2) and oxygen (O2) are exchanged in the lungs and
tissues.
Language of the Discipline
Circulatory System:
A group of organs that transports needed
materials throughout the body.
Input: Circulatory System
Transports oxygen and nutrient rich
blood to cells.
Takes away waste.
Includes: heart, blood vessels, and
blood.
Input: The Heart
Heart: an organ that pumps blood to the
body.
Animal cells need oxygen and nutrients to
survive.
Animals made up of many cells have
structures that carry oxygen and nutrients
to each cell.
Our hearts have 4 chambers.
Input: Blood
Connective tissue:
plasma, red blood
cells, white blood
cells, and platelets.
• Solid:
• Red blood cells:
• Carries oxygen to
cells
• White blood cells:
Plasma:
• Help fight infection
Liquid:
• Platelets:
Mostly water
• Helps blood clot
Carries nutrients
• Stops bleeding from
wounds
to cells
Takes waste awayBill Nye the Science Guy!
Input: Circulatory Cycle
1. Blood leaves the heart through blood vessels called
arteries.
* Arteries = Away!
2. Arteries lead to small blood vessels called capillaries.
3. In the capillaries, materials are exchanged between the
blood and body cells.
Capillaries have thin walls and come into direct contact
with every body cell.
b. Materials move through the thin walls and cross the
membranes of the cells.
a.
Input: Circulatory Cycle Cont’d
c. Nutrients, oxygen, and waste moves from areas
of high concentration to areas of low
concentration.
d. Nutrients and oxygen move from the capillaries
into the cells where they are needed.
e. Waste materials move from the cells into the
capillaries.
4. Capillaries lead to large blood vessels called veins.
5. Veins return blood to the heart.
* Veins = Towards!

Quick Review
1. Arteries
2. Capillaries
3. Exchange:
1. Needed materials go into cells.
2. Waste moves out of the cells.
4. Veins
5. Returns to the heart

more difficult.

Language of the
Discipline
Respiratory System:
A group of organs and tissues that
exchanges oxygen and carbon
dioxide between your body and the
environment.
Diaphragm:
Located near the bottom of
your rib cage and helps pull
air into your body.
Lang. of the Disc. Cont’d
Trachea:
Air travels from nose/mouth into
trachea and then branches into
smaller and smaller tubes into
lungs.
Input: Respiratory System
The lungs are the main organ of the
respiratory system.
Your body uses a lot and needs a lot
of energy.
In order to get this energy, your body
needs oxygen.
Input: Respiratory/Circulatory System
The respiratory system works very closely with the
circulatory system.
The oxygen that you inhale moves from your lungs
(respiratory system) into the blood (circulatory
system).
At the same time, carbon dioxide moves from the
blood (circulatory system) to the lungs (respiratory
system) and leaves the body when you exhale.
This “exchange” takes place within the air
sacs/alveoli.

Summarize…
In your own words describe why the respiratory system
is important.
How does the respiratory and circulatory system work
together?
Input: Respiratory/Circulatory Steps
1. Air enters the nose/mouth.
2. Air passes through the trachea.
3. Air enters the lungs.
4. Air moves to the air sacs/alveoli that are
wrapped in capillaries and the
“exchange” takes place.
a. The air sacs/alveoli pass oxygen to
capillaries.
b. The capillaries pass carbon dioxide to
the air sacs/alveoli.
Input: Respiratory/Circulatory Steps
5. Body exhales and gets rid of carbon
dioxide.
6. Oxygen rich blood travels back to the heart!
7. From the heart the respiratory/circulatory
system continues.
