1. Cardiovascular System
Essential Questions: How does the cardiovascular system transport materials to and from your cells?

2. What do we already know about the heart and blood ?

3. Topic #1: Purpose and Parts
Cardiovascular system purpose = transports materials around your body. Ex. = Oxygen and energy

4. Topic #1: Purpose and Parts
Your cardiovascular system is like the highway for your body’s materials

5. What would happen if our bodies didn’t have blood?
Partner Talk: 1 minute
What would happen if our bodies didn’t have blood?

6. Topic #1: Purpose and Parts
Three main parts: blood, heart, blood vessels

7. Topic #2: Blood! Body contains 1.5 gal of blood
Blood = Plasma + Red blood cells + white blood cells + platelets

8. Topic #2: Blood
Plasma: Liquid mixture of water, minerals, nutrients, sugar, proteins, ext.

9. Topic #2: Blood Red blood cells: Deliver oxygen to cells
White blood cells: Defend body against viruses
Platelets: Parts of bone marrow cells in plasma that stick together to stop bleeding

10. Partner Talk
Partner in odd # seat: What would happen if you had a low white blood cell count? Partner in even # seat: What would happen if you did not have any platelets?

11. Drawing Break (3-5 minutes) Blood pic. on pg 31 of textbook
In the top left hand box, draw a diagram of blood. - Include labels of plasma, red blood cells, white blood cells, and plasma. - Color if time

12. Topic #3: Heart Heart structure: - 2 sides divided by a wall
- 4 sections/chambers total (2 on each side)

13. Topic #3 Heart Heart: Pumps blood in 2 directions
Pumps blood without oxygen to lungs (left side)
Pumps blood with oxygen to rest of body (right side)

14. Drawing break: 3-5 minutes Pics on pg. 32 of textbook
Draw a diagram of your heart
Label 4 chambers, what which side pumps oxygen rich and oxygen poor blood

15. Topic 4: Vessels Vessels = Tubes that deliver blood
3 types of vessels:
1.) Arteries – Carry blood away from heart
2.) Capillaries – Very thin (1 cell thick) vessels that deliver oxygen/nutrients/water to other tissue
3.) Veins – Carry blood back to the heart

16. Topic 4: Vessels
Arteries

17. Topic 4: Vessels
Capillaries

18. Topic 4: Vessels
Veins

19. Partner Talk
Odd # Partner: What is the difference between a vein and an artery Even # Partner: Discuss why we have roughly the same amount/distribution of veins and arteries but a way higher number of capillaries

20. Drawing Break #3 (3-5 mins) See pg. 33 in textbook
Draw a vein, an artery, and a capillary
Color if time

21. Drawing Break #4
Color your gingy man and glue him into the fourth box.
Think: What is your gingy man missing?
