b. increased phagocytes in the affected area.
c. decreased capillary permeability.
d. general vasoconstriction.
A
- The warmth and redness related to the inflammatory response results from:

c. 2, 3, 5, 4, 1
d. 3, 2, 5, 1, 4
D
- The process of phagocytosis involves the:
a. ingestion of foreign material and cell debris by leukocytes
b. shift of fluid and protein out of capillaries.
c. formation of a fibrin mesh around the infected area.
d. movement of erythrocytes through the capillary wall.
A
- Systemic effects of severe inflammation include:
a. erythema and warmth.
b. loss of movement at the affected joint.
c. fatigue, anorexia, and mild fever.
d. abscess formation.
C
- The term leukocytosis means:
a. increased white blood cells (WBCs) in the blood.
b. decreased WBCs in the blood.
c. increased number of immature circulating leukocytes.
d. significant change in the proportions of WBCs.
A
- Which of the following statements applies to fever?
a. Viral infection is usually present.
b. Heat-loss mechanisms have been stimulated.
c. It is caused by a signal to the thalamus.

D
- Mechanisms to bring an elevated body temperature down to the normal level include:
a. general cutaneous vasodilation.
b. generalized shivering.
c. increased heart rate.
d. increased metabolic rate.
A
- Replacement of damaged tissue by similar functional cells is termed:
a. fibrosis.
b. regeneration.
c. resolution.
d. repair by scar tissue.
B
- Scar tissue consists primarily of:
a. granulation tissue.
b. epithelial cells.

d. new capillaries and smooth muscle fibers.
C
- Which of the following promotes rapid healing?
a. Closely approximated edges of a wound
b. Presence of foreign material
c. Exposure to radiation
d. Vasoconstriction in the involved area
A
- Glucocorticoids are used to treat inflammation because they directly:
a. promote the release of prostaglandins at the site.
b. decrease capillary permeability.
c. mobilize lymphocytes and neutrophils.
