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.
Slide 4
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 (CO 2 ) and oxygen
(O 2 ) are exchanged in the lungs and tissues.
Slide 5
Language of the Discipline Circulatory System: A group of
organs that transports needed materials throughout the body.
Slide 6
Input: Circulatory System Transports oxygen and nutrient rich
blood to cells. Takes away waste. Includes: heart, blood vessels,
and blood.
Slide 7
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.
Slide 8
Input: Blood Connective tissue: plasma, red blood cells, white
blood cells, and platelets. Plasma: Liquid: Mostly water Carries
nutrients to cells Takes waste away Solid: Red blood cells: Carries
oxygen to cells White blood cells: Help fight infection Platelets:
Helps blood clot Stops bleeding from wounds Bill Nye the Science

Slide 9
Input: Circulatory Cycle 1. Blood leaves the heart through
blood vessels called arteries. * A rteries = A way! 2. Arteries
lead to small blood vessels called capillaries. 3. In the
capillaries, materials are exchanged between the blood and body
cells. a. 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.
Slide 10
Input: Circulatory Cycle Contd 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! The Blood Mobile Song!
Slide 11
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 Kids Health

Respiratory System
Slide 14
Anticipatory Set Run 1 lap. Run 1 lap while breathing through a
straw. Compare and contrast which was easier and which was more
difficult.
Slide 15
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 (CO 2 ) and oxygen
(O 2 ) are exchanged in the lungs and tissues.
Slide 16
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.
Slide 17
Lang. of the Disc. Contd Trachea: Air travels from nose/mouth
into trachea and then branches into smaller and smaller tubes into
lungs.
Slide 18
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.
Slide 19
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. Kids Health!
Slide 20
Summarize In your own words describe why the respiratory system
is important. How does the respiratory and circulatory system work
together?
Slide 21
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.
Slide 22
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. Education Foundation Video Respiratory Rap! Paraphrase
the above 7 steps and illustrate!
