  1. April 12, 2013 (B Day) Agenda • DSJ #36 • Human Body Corporation (Persuasive Letter) • Cardiovascular System – Part 1 (Notes) • DSR #36

  2. April 15, 2013 (A Day) Agenda • DSJ #36 • Human Body Corporation (Persuasive Letter) • Cardiovascular System – Part 1 (Notes) • DSR #36

  3. DSJ #36 • Science Notebook – 12B • Prompt: Think about a subway, bus, or train. What are the purposes of these vehicles? How do they know where to go? Explain your answer in 5 sentences or more.

  4. Cardiovascular system - part 1

  5. Learning Objectives • Students will: • Explain the functions of the cardiovascular system. • Describe the function and structure of the heart.

  6. The Cardiovascular System • 1. Another name for the cardiovascular system is also known as the circulatory system.

  7. The Cardiovascular System • 2.

  8. The Cardiovascular System • 3. The cardiovascular system carries needed substances, waste products and, disease-fighting blood cells.

  9. The Heart • The heart is a hollow, muscular organ that pumps blood throughout the body.

  10. The Heart • The heart is a hollow, muscular organ that pumps blood throughout the body. • 4. Each time the heart beats, it pushes blood through the blood vessels of the cardiovascular system.

  11. The Heart • The right side of the heart is completely separated from the left side by a wall of tissue called the septum.

  12. The Heart • 5. Each side has an upper chamber, or atrium, and a lower chamber, or ventricle.

  13. The Heart • 5. Each side has an upper chamber, or atrium, and a lower chamber, or ventricle. • There are 2atria (plural for atrium) and 2ventricles.

  14. The Heart • 5. The atria receives blood that comes into the heart.

  15. The Heart • 5. The atria receives blood that comes into the heart. • The ventricles pump blood out of the heart.

  16. The Heart • As blood flows out of the heart and toward the lungs, it passes through a valve like the one here.

  17. The Heart • 6. A flap of tissue that prevents blood from flowing backward is a valve.

  18. The Heart • 7. The group of cells that adjusts the rate of the heart beat is called the pacemaker.

  19. The Heart • When muscle cells in the ventricles contract, they exert a force on the blood.

  20. The Heart • When muscle cells in the ventricles contract, they exert a force on the blood. • 8. The force exerted by the ventricles pushes the blood out of your heart and into the arteries.

  21. Two Loop System • 9. Your body has three kinds of blood vessels – arteries, capillaries, and veins.

  22. Two Loop System • Blood circulates through the body in two loops, with the heart at the center.

  23. Two Loop System • 10. In the first loop, blood travels from the heart to the lungs where oxygen moves into the blood. This blood then goes back to the heart.

  24. Two Loop System • 11 .

  25. Two Loop System • 12. In the second loop, blood is pumped from the heart into the aorta, which is the largestartery in the body.

  26. Two Loop System • 12. In the second loop, blood is pumped from the heart into the aorta, which is the largestartery in the body. • Blood passes throughout the body through the aorta and then returns to the heart.

  27. Glue in SNB **Please remember to use only TWO drops of glue!!** If everyone uses only TWO drops, a lot of glue is saved over time…. • 11B– Human Body Corporation

  28. DSR #36 • Science Notebook – 12B (Under DSJ #36) • Prompt: What 3 structures make up the cardiovascular system? What 3 things are carried throughout the body by this system? What are the 3 kinds blood vessels?
