Chapter 22: Part Six

Various types of macrophages are derived from

monocytes.

The release of endogenous pyrogen (or interleukin-1) by active macrophages would

produce a fever.

Histamine increases blood flow and vascular permeability. This would account for all of the following changes that occur during inflammation except A) redness of the inflamed tissue. B) chemotaxis of phagocytes. C) heat of the inflamed tissue. D) movement of defense proteins and cells into the interstitial space. E) swelling of the inflamed tissue.

chemotaxis of phagocytes.

The effects of activating the complement system include all of the following except A) destruction of target cell plasma membranes. B) stimulation of inflammation. C) inhibition of the immune response. D) opsonization. E) chemotaxis.

inhibition of the immune response.

A sample of John's blood shows a high level of pyrogens. This would indicate that John

is running a fever.

An inflammatory response is triggered when

mast cells release histamine and heparin.

Microphages include

both neutrophils and eosinophils.

Plasma contains ________ special proteins that form the complement system.

more than 30

Leslie has a severe sore throat and the lymph nodes in her neck are swollen. This would indicate that

the lymph nodes contain an increased number of lymphocytes.

The classic pathway of complement activation begins when the protein C1 binds to

two antibodies attached to an antigen.
