-Foreign substance or component of a cell that stimulates immune responce
-Specific protein produced in humoral response to bind with antigen
-Antibodyies against self antigen (Autoimmune disease)
-Gland located in the mediastinum, Large in children smaller in adults. Site of maturation and proliferation of T Lymphocytes
Lymphatic Tissue
Contains many lympthocytes. Filters body fluids, removes freign matter, immune responce
Bone Marrow
Source of stem cells, leukocytes and maturation of B lymphocytes
White blood cells for phagocytosis; nonspecific defence; active in inflamitory process
White blood cells: Bind IgE, release histamine in anaphylaxis
White blood cells: Participate in allergic response
White blood cells: Migrate from the blood into tissues to become macrophages
Phagocytosis; porcess and present antigens to lymphocytes for the immune responce
Mast Cells
Relese chemical mediators such as histamine in connective tissue.
Plasma Cells
Develop from B lymphocytes and secrete specific antibodies.
B Lymphocytes
Humoral immunity-activated cell becomes an antibody-producing plasma cell or a B memory cell
T Lymphocytes
White blood cells: Cell-mediated immunity
Cytotoxic T cells
-Destroys antigens, cancer cells and virus infected cells
Memory T cells
-Remember antigen and quickly stimulate immune responce on reexposier
Helper T cells
-Activate B and T cells; controle or limit specific immune responce
NK Lymphocytes
-natural killer cells destory foreign cells, virus infected cells, and cancer cells
Chemical Mediators
-Groups of inactive proteins in the circulation that, when activated, stimulate other mediators and promote inflamation, chemotaxis and phagocytosis
Chemical Mediators
-Relesed from mast cells and basophils, cause vasodilation and edema, also cause bronchiolar and smooth muscle contraction.
Chemical Mediators
-Cause vasodilation, edema, and pain
Chemical Mediators
-Groups of lipids with varying effects, some cause inflamation, vasodilation, edema, and pain
Cytokines (messingers)
Chemical Mediators
-Includes lymphokines, monokines, interferons, and interlukins. Produced by macrophages and activated T Lymphocytes; stimulates activation and proliferation of B and T cells
Chemotacitc Factors
Chemical Mediators
-attract Phagocytes to area of inflamation
Most common antibody in the blood; Produced in both primary and secondary immune responces; activates complent; includes antibacterial, antiviral, and antitoxin
Bound to B lymphocytes in circulation and is usually the first to increse in the immune responce; activates compliment; forms natural antibodies; involved in ABO blood incompatibility reactions
Found in secretions such as tears and saliva, mucous membranes, and colostrum (breast milk) to provide protection for newborn child
Binds to mast cells in skin and mucous membranes; when linked to allergen, causes release of histamine and other chemicals, resulting in infalmation
Attached to B cells; activates B cells
Allograft (homograft)
-Tissue Transferred between members of the same species (Ex. human-human)
-Tussue transfeer between two genetically identical bodies (Ex. Identical Twince)
-Tissue tranferred from one part of the body to another part in the same person (Ex. Skin or bone)
Xenograft (heterograft)
Tussue transferred from a member of one species to a different species (EX. pig-human)
Hay fever; anaphylaxis
-IgE bound to mast cells; release of histamine and chemical mediators (causes immediate inflamation and pruritus:itching)
ABO Blood Incopatibility
-IgG or IgM reacts with antigen on cell-compliment acitvated (Causes cell lysis and phagocytosis)
Autoimmune Disorders
-Antigen-antibody complex deposites on tissue (causes inflamation and, vasculitis:inflammed blood vessles)
Contact Dermitits; transplant rejection
Antigen binds to T-lymphocytes; T-cell releases lymphokines (Causes Delayed inflammation)
