Term
Immunity is ?
Definition
  • The body's specific protective response to an invading agent or organism
  • Bone marrow
  • Thymus Gland
  • Lymphoid tissues
Term
Bone Marrow is?
Definition
  • production site of WBC's - leukocytes
  • Granular Leukocytes
  • Nongranuglar Leukocytes
Term
Granular Leukocytes are?
Definition
  • Neutrophils - inflammation
  • Eosinophils - allergic stress response
  • Basophils - allergic stress response
Term
Nongranular Leukocytes are?
Definition
  • Monocytes(macrophages)
  • Lymphocytes
Term
Monocytes are?
Definition
  • nongranular Leukocytes
  • macrophages
  • phagocytic cells
Term
Lymphocytes are?
Definition
  • differentiate into B cells or move to Thymus and mature into T cells
Term
Thymus Gland is ?
Definition
  • located mediastinum anterior to and above the heart
  • T lymphocytes
  • Helper T cells
  • Suppresor T cells
  • Cytotoxic  T cells
Term
T Lymphocytes
Definition
originally B cells from bone marrow
Term
helper T cells
Definition
From the thymus gland
Term
Suppresor T Cells
Definition
  • Turn off
  • from thymus gland
Term
Cytotoxic T Cells
Definition
  • Killer cells
  • from thymus gland
Term
Lymphoid Tissue is ?
Definition
  • Spleen
  • Lymph nodes
  • Tonsils and adenoids
Term
Spleen
Definition
contains lymphocytes and destroys RBC
Term
Lymph Nodes
Definition
removes foreign material and proliferates immune cells
Term
Tonsil and Adenoids
Definition
Tonsil and Adenoids
Term
Normal Immune Response is ?
Definition
  • Natural Immunity
  • Acquired Immunity
  • Natural Immunit Innate
Term
Natural Immunity is ?
Definition
  • normal immune response
  • Present at birth
  • Physical barriers
  • chemical barriers
  • inflammatory Response
  • WBC's role
Term
Physical barriers
Definition
skin mucous membranes cilia cough sneeze
Term
Chemical barriers
Definition
  • gastric secretions
  • mucus
  • tears/saliva enzymes
  • sebaceous sweat secretions
  • interferon
Term
Inflammatory Response
Definition
initiated by tissue injury or organisms
Term
WBC's Role
Definition
  • Phagocytic
  • humoral response
  • cellular immune response
  • complement
Term
phagocytic
Definition
  • wbc role
  • 1st line of defense involves:
    • granulocytes/macrophages
    • release histamine
    • bradykinin
    • prostagladdins
Term
bradykinin is ?
Definition
is a peptide that causes blood vessels to dilate (enlarge), and therefore causes blood pressure to lower
Term
Prostagladdins are ?
Definition
  • are substances that help the body with many different functions.
  • mediate the inflammation process and relay pain signals
Term
Humoral Response is ?
Definition
  • wbc role
  • antigen recognition by B-Lymphocyte cells with production of specific antibodies (plasma cells) and B-Lymphocyte cells with a memory for past antigen exposure (memory cells)
Term
Antigen is?
Definition
any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment such as chemicals, bacteria, viruses, or pollen. An antigen may also be formed within the body, as with bacterial toxins or tissue cells.
Term
Antibodies are?
Definition
  • Specialized cells of the immune system which can recognize organisms that invade the body (such as bacteria, viruses, and fungi).
  • large proteins called Immunoglobulins
Term
Cellular immune response is ?
Definition
  • wbc role
  • T lymphocytes attack foreign  material directly
    • cytotoxic T cells
  • or stimulate B cells and other cell types to react
    • T4
    • T1
    • T2 - helper cells
    • suppresor
    • memory
Term
Complement is ?
Definition
  • wbc roles
  • proteins produced by the liver and released when antibody-antigen complex occurs.
  • Cascade effect when activated and the cell membrane of the antigen-antibody complex causing destruction
Term
Acquired Immunity is?
Definition
  • Normal immune response
  • adapative
  • from prior exposure to an antigen
  • Passive acquired
  • Active acquired
Term
Passive acquired is ?
Definition
  • temporary and obtained from receiving the antibodies from another individual
  • immune globulin serum for exposure to hepatitis
  • breast fed infant from mother
Term
Active acquired is?
Definition
  • immunity developed by the individual from exposure to the disease or vaccination
Term
Natural Immunity is?
Definition
  • Normal immune response
  • innate present from birth and gives rapid response
    • macrophages
    • dendritic cells
    • natural killer cells
Term
Alterations in body defenses ?
Definition
  • disorders of the immune system
  • hypersensitive reactions
  • autoimmune diseases
  • neoplastic disease
  • primary immunodeficiency disorders
  • secondary immunodeficiency disorders
Term
Hypersensitive reactions are ?
Definition
  • allergies
  • anaphylactic shock
Term
Autoimmune diseases are ?
Definition
  • lupus erythematosus
  • rheumatoid arthritis
  • psoriasis
Term
Neoplastic disease
Definition
Neoplastic disease
Term
Primary immunodeficiency disorders
Definition
genetic basis
Term
secondary immunodeficiency disorders
Definition
  • result from a disease process or treatment of a disease process
  • hiv-aids
