Learning Guide: Physiology 4 Immunity
Bill Activity #53
To Think About: What is the purpose of the immune system? How does the immune system function? Why do animals
have a more developed immune system than other animals?
1st Learn About: Use text and prezi presentation Immunity to answer the following questions in your BILL.
Ch. 43 The Immune System: Campbell’s Biology 9th edition
The Immune System
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:
Barriers, Traps, Elimination, Non-specific patrolling cells
3. How is immunity acquired during a vertebrate’s life cycle?
4. Compare B-cells and T-cells.
5. How is it possible that functionally infinite variations of antibodies can be made from one set of genes?
6. Explain the role of Helper T-cells in the immune system.
2nd Interact: Watch Mr. Anderson’s Immune System Video and take notes in your BILL.
Make Sure You Can Explain:
 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).
