Unformatted text preview: sistant bacteria, which will multiply, producing an antibiotic-resistant colony. This is an
example of natural selection in action.
• Suppose a disease-causing bacteria lands on the skin. List the defenses that would 1) prevent the bacteria
from invading the body in the first place, 2) immediately respond to the bacteria. If the bacteria survives
these sets of defenses, what is triggered next?
• Describe the roles of the following in nonspecific defenses: lysozymes, mucus, ciliary action, phagocytic
cells, fever, inflammatory response.
• Describe the roles of mast cells and histamines in immune response.
• Distinguish between the terms antibody, antigen, and antibiotic.
• Describe what antibodies are and how they are produced.
• Describe the interaction between the macrophage and the helper T cell when an antigen is discovered.
• The T cell signals clonal selection among B cells. Describe this process and its function.
• Describe the role of cytotoxic T cells (“killer T cells”) in the immune response.
• Describe the role of memory T cells and memory B cells in long-term immunity. What happens if the same
antigen is encountered again?
• Describe how antibiotics and vaccines assist the immune response.
• How do new strains of influenza (“the flu”) develop?
• Describe how malfunctions of the immune system produce allergies and autoimmune diseases.
• Describe how the HIV virus disables the human immune system and how cancer overwhelms the immune
• “Introducing the bloody characteristics of specific immunity” http://science.nhmccd.edu/biol/inflam.html is an
animated tutorial of the immune response.
• “Immune system” http://highered.mcgraw-hill.com/sites/0072437316/student_view0/chapter48/
animations.html# has several audio-visual tutorials about immunity.
• “HIV in Action” http://www.pbs.org/wgbh/nova/aids/action.html is a series of online films from PBS with
animations to show how HIV infects human immune cells....
