Edition 5 exam with correct answers
Component: Antigen Function: Foreign substance or component of cell that stimulates an
immune response CORRECT ANSWER Component: Antibody Function: Specific protein
produced in a humoral response to bind with an antigen CORRECT ANSWER Component:
Autoantibody Function: Antibodies against a self-antigen; attacks body's own tissues
CORRECT ANSWER Component: Bone marrow Function: Source of stem cells,
leukocytes, and maturation of B lymphocytes CORRECT ANSWER Component: Thymus
Function: Gland located in the mediastinum, large in children, decreasing size in adults;
site of maturation and proliferation of lymphocytes CORRECT ANSWER Component:
Lymphatic tissue Function: Contains many lymphocytes; filters body fluid, removes foreign
matter, part of immune response CORRECT ANSWER Cell: Neutrophils Function:
White blood cells-for phagocytosis; nonspecific defense, active in inflammatory process
CORRECT ANSWER Cell: Basophils Function: White blood cells-bind immunoglobulin
E; release histamine in anaphylaxis CORRECT ANSWER Cell: Eosinophil Function:
White blood cells-participate in allergic responses CORRECT ANSWER Cell: Monocytes
Function: White blood cells-migrate from the blood into tissues to become macrophages
CORRECT ANSWER Cell: Macrophages Function: Phagocytosis; process and present
antigens to lymphocytes for the immune response CORRECT ANSWER Cell: Mast cells
Function: Release chemical mediators such as histamine in connective tissue CORRECT
ANSWER Cell: B lymphocytes Function: Humoral immunity-activating cell becomes an
antibody-producing plasma cell or a B memory cell CORRECT ANSWER Cell: Plasma cells
Function: Develop from B lymphocytes and secrete specific antibodies CORRECT
ANSWER Cell: T lymphocytes Function: White blood cells: cell-mediated immunity
CORRECT ANSWER Cell: Cytotoxic or killer T cells Function: Destroy antigens, cancer
cells, virus-infected cells CORRECT ANSWER Cell: Memory T cells Function: Remember
antigens and quickly stimulate immune response on re-exposure CORRECT ANSWER Cell:
Helper T cells Function: Activate B and T cells; control or limit specific immune response
