In this procedure, you will be tracing two invaders: bacteria in the extracellular fluid and a virus that has infected cells. To keep
things simple, you will trace the main pathway and the main immune response to the pathogen. Do note, however, that the actual
response is much more complex, and your instructor may wish you to include more information. You are provided with hints
and the number of steps you should aim to include for each organism, but you will likely want to consult your textbook for
more help. After you have completed the activity, answer Check Your Understanding Questions 5 and 6 (p. 586).
