13.E: Humoral Immunity (Exercises)

 

These are homework exercises to accompany Kaiser's "Microbiology" TextMap. Microbiology is the study of microorganisms, which are defined as any microscopic organism that comprises either a single cell (unicellular), cell clusters or no cell at all (acellular). This includes eukaryotes, such as fungi and protists, and prokaryotes. Viruses and prions, though not strictly classed as living organisms, are also studied.

13.1: Antibodies (Immunoglobulins)

  2. In terms of infectious disease, state what humoral immunity is most effective against. (ans)

13.2: Ways That Antibodies Help to Defend the Body

  • List 9 ways that antibodies help to defend the body.

13.3: Naturally and Artificially Acquired Active and Passive Immunity

  1. Define the following:

    2. passive immunity
  2. Study the material in this section and then write out the answers to these questions. Do not just click on the answers and write them out. This will not test your understanding of this tutorial.
