Cell that produces huge numbers of the same antibody (immunoglobulin)
Plasma cell
How do plasma cells assist with humoral immunity
Plasma cells produce interferons
Slows or stops B and T cell activity once infection has been conquered
Regulatory T cell
The _____ duct drains lymph from the right arm and the right side of the head and thorax
Right lymphatic
The inflammatory process begins with release of chemicals, which do all of the following EXCEPT
Stimulate release of lysosome
The process by which antibodies bind to specific spots on bacterial exotoxins (toxic chemicals secreted by bacteria) to block their harmful effects is called
Neutralization
Harmful or disease-causing microorganisms from which nonspecific defense protect the body are called
Pathogens
Which of the following is NOT an autoimmune disease
AIDS
Redness, heat, swelling, and pain are the four most common indicators of
Acute inflammation
Which antibody-antigen interaction results when a foreign blood type is transfused and clumped
Agglutination
A lymph node is indicated by
B
The thymus is indicated by
B
Lymph fluid and some plasma proteins originate (escape) from the
Blood vascular system
B cells develop immunocompetence in the
Bone marrow
The lymphoid organ that destroys worn-out blood cells is indicated by
C (spleen)
What is the chief way the body responds to antigens
Complement fixation
Kills virus-infected cells, cancerous cells, and is involved in graft rejection
Cytotoxic T cell
A lymph capillary is indicated by
D
The peyer's patches are indicated by
D
Excess accumulation of fluid, which impairs the exchange of materials within the tissues, is called
Edema
What does fever accomplish
Fever inhibits bacterial reproduction and speeds the repair process
Which one of the following is NOT one of the antibody classes
IgB
Regardless of whether it matures into a B cell or a T cell a lymphocyte that is capable of responding to a specific antigen by binding to it is said to be
Immunocompetent
What inhibits viruses from entering and attacking healthy cells
Interferons
The adaptive (specific) defense system
Issues an attack specific to particular foreign substances
The third line of defense involves the adaptive response mediated by
Lymphocytes
May exist in the body for years and enable a quick response to subsequent meetings with the same antigen
Memory cell
Due to a recent respiratory illness from a viral infection, Jennifer has now developed
Naturally acquired active immunity
Lymphocytes are trained to be self-tolerant of
The body's own cells
Which one of the following is NOT true of the constant (C) regions of antibodies
The constant regions form an antigen-binding site
Chemotaxis is best described as
The movement of cells along a chemical gradient
