  3. EPO – Produced by Kidneys to help increase the production of red blood cells • Importance of red blood cells • Transport oxygen to tissues • Why is this important? How is this an unfair advantage? Lance Armstrong

  4. Corticosteroids • Testosterone Lance Armstrong

  5. Read Handout about Blood Pressure • Understand it’s importance Homework

  6. Heart • Blood • Blood Vessels Circulatory System

  7. What are the 3 types of blood vessels? • Arteries • Capillaries • Veins Blood Vessels

  8. Oxygenated blood • Carries blood from heart to tissues • Thick walls to withstand pressure • Blood pressure • Will learn to take BP on Thursday’s class Arteries

  9. Very small vessels that help oxygen into the tissues • Blood cells flow ‘single file’ • Very thin walls • What is the importance of thin walls? What happens to the oxygen? Capillaries

  10. This blood is returned to the heart • Needs to be reoxygenated • Flows against gravity • Valves • Less pressure • How can this blood get back to the heart? Veins

  11. Transports oxygen, nutrients and other substances throughout the body, and removes wastes from tissues Circulatory System

  12. What is the importance of transporting oxygen? • Nutrients? • Removing waste? Circulatory System

  13. Read Handout about Blood Pressure • Understand it’s importance Homework
