Presentation Transcript

  1. Immune System A presentation by Alison, Donika & Lauren

  2. What does the immune system do? • Protects against disease • It identifies, then kills pathogens and tumor cells.

  3. What’s the Big Idea? • The immune system is a very complex system and goes into a lot of depth • This system fights off millions of biological and chemical threats on a daily basis and ensures our survival

  4. Immune System What it protects us from:

  5. Terms to know before we begin… • Antigens- attack antibodies and make them less effective • Pathogens-cause harm and illness by attacking cells • Antibodies- blood protein that is specified to attack a specific antigen

  6. What’s it composed of? • Specialized Cells • Proteins • Tissues • Organs

  7. How does it work? • Your WBC’s (also called leukocytes) are formed in your bone marrow, which specialize into lymphocytes. These lymphocytes specialize into “T-Cells” and “B-Cells” • These cells work together to fight off foreign substances. The “T-Cells” subdivide and these cells keep the balance by amplifying production of “B-Cells” and the decrease of this production to maintain homeostasis (a constant state)

  8. Important Organs and Tissues • Spleen • Lymph • Lymph Nodes • Bone Marrow • Leukocytes (WBC’s) • Lymphocytes • Neutrophils • Basophils • Monocytes • Phagocytes • “T-Cells” • “B-Cells” • Thymus Gland

  9. How Does it Connect? Your Immune system connects with all of your body’s systems and works to keep a certain state of homeostasis.

  10. Here are some ways to remember this stuff! “T” stands for Thymus (which is where the “T-Cells” mature) -The T cells subdivide into 4 parts. “B” stands for Bone Marrow (where most of the “B-Cell” maturation takes place)

  11. Here are some questions that’ll rattle your mind! 1. From what you learned, why do you think people have allergies? 2. How do you think the immune system works with the circulatory system? 3. Why do you need to get a flu shot every year, but the chickenpox vaccine only once? http://www.youtube.com/watch?v=De95q_bC894
