3. Heart- pumps the blood throughout the body
Cardiovascular System- system of heart and blood vessels working together
Heart- pumps the blood throughout the body
Lungs- helps you breathe in oxygen and exhale carbon dioxide
Oxygen- a gas that you inhale that the blood takes from the lungs 2

4. Arteries- carries blood away from the heart
Carbon Dioxide- a gas that the blood brings from the body to the lungs for you to exhale
Arteries- carries blood away from the heart
Veins- carries blood toward the heart
Asthma- a condition that keeps people from breathing well
Nutrients- food solution carried by the blood to the body 2

5. THE HEART
Picture of car and getting gas
The heart is located in the middle of the body. It is about the size of your fist. 2

6. THE HEART
The heart pumps blood all over the body. When you exercise, the heart beats faster to pump blood to the muscles. When you sleep, the heart slows down. This is so the heart and body can rest. 2

7. The lungs are on each side of the heart. They help you breathe.

The lungs are on each side of the heart. They help you breathe. 2

8. The heart and lungs work together and are protected by the ribs
The heart and lungs work together and are protected by the ribs. When you exercise, the lungs and heart work faster to deliver oxygen to your muscles. 2

9. The lungs breathe in oxygen and breathe out carbon dioxide.2

10. The heart pumps blood.
The blood picks up oxygen from the lungs and delivers oxygen throughout the body.
Blood with oxygen
Blood without oxygen 2

11. Where does the blood travel after it leaves the lungs?

12. The blood picks up nutrients from the digestive system
The blood picks up nutrients from the digestive system. It delivers the nutrients on its route through the body. 2

13. Asthma
Asthma is a condition that keeps people from breathing well. It is not contagious so you can not catch it from someone that has it.

17. What does your blood pick up in the lungs?
Food = V-sit
Muscles = Frog Jumps
Oxygen = Push ups
Students should jog in place, 2

18. Oxygen = Push ups

19. What does the blood bring back through the heart to the lungs to be exhaled?
Carbon Dioxide = V-sit
Muscles = Frog jumps
Nutrients = Push ups 2

20. Carbon Dioxide = V-sit
Oxygen = Push ups
