1. Circulatory & Respiratory System

2. 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.

3. 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.

4. Language of the Discipline
Circulatory System:
A group of organs that transports needed materials throughout the body.

5. Input: Circulatory System
Transports oxygen and nutrient rich blood to cells.
Takes away waste.
Includes: heart, blood vessels, and blood.

6. 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.

7. 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

8. Input: Circulatory Cycle
Blood leaves the heart through blood vessels called arteries.
* Arteries = Away!
Arteries lead to small blood vessels called capillaries.
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.
Materials move through the thin walls and cross the membranes of the cells.

9. Input: Circulatory Cycle Cont’d
Nutrients, oxygen, and waste moves from areas of high concentration to areas of low concentration.
Nutrients and oxygen move from the capillaries into the cells where they are needed.
Waste materials move from the cells into the capillaries.
Capillaries lead to large blood vessels called veins.
Veins return blood to the heart.
* Veins = Towards!

12. Respiratory System

13. Anticipatory Set Run 1 lap. Run 1 lap while breathing through a straw.
Compare and contrast which was easier and which was more difficult.

14. 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.

15. 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.

16. Lang. of the Disc. Cont’d Trachea:
Air travels from nose/mouth into trachea and then branches into smaller and smaller tubes into lungs.

17. 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.

18. 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.

19. Summarize…
In your own words describe why the respiratory system is important.
How does the respiratory and circulatory system work together?

20. Input: Respiratory/Circulatory Steps
Air enters the nose/mouth.
Air passes through the trachea.
Air enters the lungs.
Air moves to the air sacs/alveoli that are wrapped in capillaries and the “exchange” takes place.
The air sacs/alveoli pass oxygen to capillaries.
The capillaries pass carbon dioxide to the air sacs/alveoli.

21. Input: Respiratory/Circulatory Steps
Body exhales and gets rid of carbon dioxide.
Oxygen rich blood travels back to the heart!
From the heart the respiratory/circulatory system continues.
