  1. Part 3: What’s In That Stuff? Fuel For Your Cells

  2. Objectives: Students Will: • Identify the components of blood. • Describe the functions of each part of the blood. • Identify which blood types are compatible in a blood transfusion. Homework: • Complete Part 3 in your packet.

  3. Recognize and explain that human beings, like other organisms have complex body systems of cells,tissues, and organs that interact to support an organisms growth and survival. VSC Content Standard: -Describe and explain that the complex set of systems found in multicellular organisms are made up of different kinds of tissues and organs which are, in turn, composed of differentiated cells-Select several body systems and explain the role of cells, tissues, and organs in the systems selected that effectively carry out a vital function for the organism, such as:Obtaining food and providing energy, Defense, Reproduction, Waste Removal, Breathing

  4. Lesson Question: What’s in your blood?

  5. Engage your thinking... 1. What do you think is in your blood? • Share and compare your ideas with your group.

  6. Explore • Now, explore the following website and your text for the parts of the blood and their functions. • As you explore, fill in the chart on page 3 (explore) in your packet. http://www.blood.co.uk/visually_impaired/vi_e17compn.html Human Biology and Health • Section 3 – Blood and Lymph pp. 113-119

  7. Components of the Blood

  8. What’s in the Blood? • Plasma • Red Blood Cells • White Blood Cells • Platelets

  9. Components of the Blood **All of this stuff floats around in the Plasma!!!!!

  10. Red Blood Cells

  11. White Blood Cells & Platelets

  12. Plasma • Plasma- Carries materials, molecules that come from the breakdown of digested food. • Proteins make it yellowish in color • Carries vitamins and minerals • Carries chemical messages • About 55% of blood is made up of plasma

  13. Red Blood Cells • Red Blood Cells- Take up the oxygen from your lungs and deliver it to the rest of your body • Are produced in the bone marrow • Mostly made of hemoglobin • Hemoglobin binds with oxygen in the lungs and releases it as it travels through the body. • Picks up some carbon dioxide, but most is carried by the plasma

  14. White Blood Cells • White Blood Cells- These are the body’s disease-fighters • Recognize invaders and alert the rest of the body • Produce chemicals to fight • Only one white blood cell for every 500/1000 red blood cells • Bigger than RBC’s

  15. Platelets • Platelets- These are cell fragments that an important part in forming clots. • Produce a chemical called Fibrin • Fibrin weaves a net of tiny fibers across the cut in the blood vessel. • The “net” traps the blood cells • Clot Forms, bleeding stops

  16. Components of the Blood **All of this stuff floats around in the Plasma!!!!!

  17. Explain • Using information from today’s investigation, Explain what parts of the blood carry oxygen and which parts fight disease.

  18. Extend your knowledge • Why must doctors know what “blood type” someone is if they are injured and need blood? • Discuss with your groups. • Read pages 116-117 “Blood Types” to answer the following: • What blood type is the universal donor? • What blood type is the universal recipient?

  19. What’s your type? (extension)

  20. Extend your knowledge • If you were a doctor and a patient needed blood, do you think you would be able to give them the right type? • What could happen if you were wrong? • Click HERE to take the challenge.

  21. Evaluate • In each of the following situations, write which part of the blood is most important: • A runner almost out of breath after a race • A person with an infected splinter • Someone who just got cut • Carrying digested food to your cells

  22. Evaluate yourself… Can you: • Identify the components of blood? • Describe the functions of each part of the blood? • Identify which blood types are compatible in a blood transfusion?

  23. Homework • Complete Part 3 in your packets.
