  1. ATB Why do people feel faint if they stand up too fast?

  2. Circulatory System Components: heart, blood vessels, lungs Functions: • Transports nutrients, gases (carbon dioxide and O2), waste, water, hormones • Distributes heat Maintains homeostasis: maintains correct amounts of nutrients, gases, and wastes and correct temperature.

  3. Arteries vs. Veins - Arteriescarry oxygenated blood from the heart to the body - Veinscarry blood towards the heart for purification.

  4. Blood Pressure Blood pressure is the pressure exerted by circulating blood on the walls of blood vessels

  5. Heart Structure

  6. 1. aorta

  7. 1. aorta2. superior vena cava3. right pulmonary artery (to lungs)4. right pulmonary veins (from lungs)

  17. Heart Rate Lab Objectives • Calculate your heart rate while laying, sitting, standing, and after exercise. • Compare your resting (sitting) heart rate with the class average.

  18. What’s Your Heart Rate?

  19. What happens to heart rate during exercise? WHY??

  20. Does being “in shape” influence your heart rate?

  21. The Effect of Caffeine on Heart Rate

  22. The Effect of Caffeine on Heart Rate

  23. The Effect of Temperature on Heart Rate

  24. The Effect of Temperature on Heart Rate
