1. Why do you think specificity; heterogeneity (diversity), memory, and self-vs. Oneself recognition is vital to the immune system?
2. Define phagocytosis. How do some bacteria avoid or survive the action of phagocytes? How does the phagocyte arrive at the site where it is needed? What happens to a phagocyte after the majority of microorganisms and damaged tissue have been eliminated?

3. The “clichĂŠ” “an ounce of prevention is worth a pound of cure” means that preventing a disease is less costly economically and to the health of the host than treating the disease once it has occurred. Draw a flow chart (or list) showing the connections between reservoirs of infection; modes of transmission; host susceptibility factors, and portals of entry. These are the steps in the disease cycle that precede the infection of the host. Are there ways of preventing host infection by halting the pathogen at these points? Discuss each step, and what measures can be used to eliminate the treat of potential disease at each point.
