A young man is struck on the cheek by a baseball and sustains an injury in which the skin is not broken and the cheekbone is not fractured. He develops an acute inflammation in the injured area. Which of the following is NOT part of the acute inflammatory process? A. Leakage of fluid through permeable capillaries into the connective tissue of the cheek B. Congestion of tissues caused by dilation of capillaries C. Accumulation of leukocytes in the injured area D. Accumulation of plasma cells and formation of immunoglobulins

D. Accumulation of plasma cells and formation of immunoglobulins

A patient has a swollen ear caused by a bacterial infection. Which of the following is not a feature of the inflammatory process? A. Leakage of fluid through permeable capillaries into the loose connective tissue of the ear B. Congestion of tissues because of dilation of capillaries C. Redness of skin because of increased blood flow through the inflamed tissues D. Reduced blood flow to tissues because of vasoconstriction of capillaries in the area of inflammation

D. Reduced blood flow to tissues because of vasoconstriction of capillaries in the area of inflammation

The term virulence refers to __________. A. a disease caused by a viral pathogen B. a disease likely to be fatal to its host C. an organism that causes disease in humans D. the ease with which a pathogenic organism can overcome host defenses

D. the ease with which a pathogenic organism can overcome host defenses

True/False A pathogenic organism with low virulence does not produce disease in humans.

False

True/False A serous exudate contains a high concentration of protein.

False

True/False All inflammation results in scar formation.

False

True/False Complement is activated only by the antigen-antibody interaction.

False

True/False Inflammation always subsides when the harmful agent that caused it is eliminated.

False

True/False Mediators of inflammation are biologically active compounds present in the cells or blood plasma.

False

True/False Monocytes and macrophages rush to the area of cell injury at the beginning of an acute inflammation, but are not active in chronic inflammation.

False

An infection that spreads from its original site to involve the regional lymph nodes is called what? A. An abscess B. Lymphadenitis C. Cellulitis D. Lymphangitis

Lymphadenitis

Which of the following is not a mediator of inflammation? A. Prostaglandins B. Histamine C. Bradykinins D. Gamma globulin antibodies E. Products of complement activation

Products of complement activation

True/False Extensive destruction of tissue resulting from inflammation is often followed by scarring that may impair the function of the tissue in which the scarring has occurred.

True

True/False Interaction of antigen and antibody activates a series of blood proteins called complement, and products of complement activation function as mediators of inflammation.

True

True/False Resolution occurs when an inflammation is mild and the tissue returns to normal without any need for repair.

True

True/False The ability of the body's defenses to fight off a pathogenic organism depends on both the virulence of the organisms and the resistance of the infected person.

True

True/False The inflammatory reaction is the same no matter what kind of injury is present, because the injury itself does not directly cause the reaction.

True

True/False The release of mediators from any source can trigger not only inflammation, but also the release of other mediators.

True
