Approximately 30-60 minutes after being bitten by a “bug”, a 26-year-old man noticed a localized swelling and erythema in the affected area. The edema is most likely the result of:
A. Altered plasma osmotic pressure

Liz notices that shortly after cutting her arm accidentally the area around the cut is turning red and feeling hot. Which immune system defense is Liz experiencing?
A. inflammation
B. white blood cell clotting
C. skin
D. fever
What is the function of a basophil?
A. Plays a major role in allergic response by producing histamine; also produces heparin to control blood clotting
B. Functions specifically to combat parasitic infection, they also help to promote inflammation and play a role in allergic reactions
C. One of the first responders in the immune system, it phagocytoses pathogens and may present the phagocytosed antigens to other immune cells
D. Helps the blood clotting process by gathering at the site of an injury, sticking to the lining of the injured blood vessel, and forming a platform on which blood coagulation can occur
E. Functions in transport and gas exchange
This cell type functions specifically to combat parasitic infections but also helps to promote inflammation and plays a role in allergic reactions
A. Basophil
B. T lymphocyte
C. Eosinophil
D. Thrombocyte
E. Neutrophil
What would you consider to be the purpose of the body’s defense system?

B. To only destroy pathogens in the body.
C. To only stop pathogens from getting into our body.
