AP Biology Video Assignment: The Immune System Instructions: ● Open the presentation. ● Watch the embedded video clips and move through the embedded content. ● Answer the “Questions to answer”. ● Make sure you understand the “Things you should make sure you understand”. ● View the “Supplementary Resources”. ● Write down any questions that you have about the material…and bring them to class to review! Topic Presentation: click here or website: http://prezi.com/nvaoowj3p8jz/ap-bio-physiology-4-immunity/ Supplementary Resources: Videos by Paul Anderson: www.youtube.com/bozemanbiology “The Immune System” “Plant and Animal Defenses” “Cell Communication” Questions to answer: 1. Why are defense systems needed in multicellular organisms? 2. Explain the physiological structures in vertebrates that serve each of the following defense purposes: a. barriers b. traps c. elimination d. non-specific patrolling cells 4. How is immunity acquired during a vertebrate’s life cycle? 5. Compare B-cells and T-cells. 6. How is it possible that functionally infinite variations of antibodies can be made from one set of genes? 7. Explain the role of Helper T-cells in the immune system. Things you should make sure you understand: ● ● ● ● ● The defenses of bacteria, plants, invertebrates and vertebrates. The interplay between the vertebrate innate and adaptive immune systems. The process of how a specific immune reaction is developed and how specific immune defenses function. The causes, symptoms, and treatments of immune system disorders. How and why vaccines work (and why they don’t always).
