surveillance
G. Inflammation
H. Interferons

______ Enzymes present in some secretions that have antibiotic properties
______ Cells that engulf and destroy pathogens and foreign materials
______ Neutrophils & eosinophils
______ Large, actively phagocytic cells derived from monocytes
______ Movement of white blood cells through the walls of capillaries by squeezing
between adjacent epithelial cells
______ Movement of cells toward or away from a chemical stimulus
______ Constant monitoring of normal tissues by NK cells
______ Small proteins released by activated lymphocytes, macrophages, & cells
infected with viruses; cause cells to produce proteins that interfere with viral
reproduction
______ Chemical messengers released by tissue cells to coordinate local activities;
hormones of the immune system; released to alter activities of cells and tissues
throughout body
______ Plasma proteins that interact in a chain reaction following exposure to
activated antibodies or to surfaces of certain pathogens; promote cell lysis,
phagocytosis and other defense mechanisms
______ Localized tissue response to injury; characterized by swelling, redness,
warmth, pain, and some loss of function
______ Maintenance of body temperature above 99 degrees Farenheit
______ Circulating proteins that can reset the thermostat in the hypothalamus and
cause a rise in body temperature

7. Listed below are characteristics of the primary and secondary responses to a
specific antigen. Determine if the statement is true of the primary response (1) or
the secondary response (2.)
______ Initial response to antigen
______ Does not appear immediately
______ Gradual, sustained rise in concentration of circulating antibodies
______ Antibody activity peaks several weeks after exposure to antigen
______ Appropriate B cell must be activated and, once activated, must
divide and differentiate into plasma cells
______ Activates memory B cells
______ Very rapid increase in antibody activity and concentration
______ Memory B cells divide and differentiate into plasma cells
______ Produces a much faster and stronger response
______ Can be substituted with immunization
