Answer to Question 1

The three phases are alarm, resistance, and exhaustion. During the alarm phase, energy reserves are mobilized and the body prepares itself with fight or flight responses. During the resistance phase, glucocorticoids are released to (1 ) mobilize lipid and protein reserves, (2 ) conserve glucose for neural tissue, (3 ) elevate and stabilize blood glucose concentrations, (4 ) conserve salts and water, and (5 ) lose K+ and H+. During the exhaustion phase, homeostatic regulation breaks down. Epinephrine plays a dominant role in the alarm phase and glucocorticoids are dominant in the resistance phase.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
