QUESTION 1 zm




Which action is a purpose of the inflammatory process?

c. To prevent infection of the injured tissue

d. To create immunity against subsequent tissue injury

ANSWER

C. If the epithelial barrier is damaged, then a highly efficient local and systemic response (inflammat

ion) is mobilized to limit the extent of damage, to protect against infection, and to initiate the repair

ANSWER

B. The coagulation (clotting) system is a group of plasma proteins that form a fibrinous meshwork a

d. Lysis of bacterial cell membranes
zm zm zm zm zm




ANSWER

D. The complement cascade can be activated by at least three different means, and its products have

four functions: (1) anaphylatoxic activity, resulting in mast cell degranulation, (2) leukocyte chemot

axis, (3) opsonization, and (4) cell lysis.

QUESTION 7 zm




What is happening during opsonization?
zm zm zm zm




ANSWER

During opsonization opsonin binds to a pathogen, then phagocytes are attracted, and the pathogen is
zm zm zm zm zm zm zm zm zm zm zm zm zm zm



opsonized (destroyed). It is bound with the antibody IgG.

QUESTION 8 zm




How does the chemotactic factor affect the inflammatory process?
zm zm zm zm zm zm zm zm



a. By causing vasodilation around the inflamed area

b. By stimulating smooth muscle contraction in the inflamed area
zm zm zm zm zm zm zm zm zm



c. By directing leukocytes to the inflamed area

ANSWER

C. Two chemotactic factors, neutrophil chemotactic factor (NCF) and eosinophil chemotactic factor of
