primary intervention - answerremoves risk factors, so diseases do not occur

advanced pathophysiology final exam
examples of primary interventions - answerimmunizations, seat belts, helmets

secondary interventions - answerdetecting disease when still curable

examples of secondary interventions - answerpap smears, routine blood screens,
chemotherapy

tertiary interventions - answerpreventing further deterioration or reducing complications
of disease

examples of tertiary interventions - answerbeta blockers following MI, chemo, radiation

homeostasis - answerproperty of a system in which variables are regulated so that
internal conditions remain stable and relatively constant; examples include the stability
of the human body's environment in response to changes in external conditions

mitochondria - answercellular powerhouse; cellular respiration; convert ingested
substances to ATP (cellular metabolism)

endoplasmic reticulum - answerprotein synthesis and fat metabolism

ribosomes - answersite of protein synthesis

golgi apparatus - answerpackages and modifies proteins from the ER for secretion;
produces lysosomes; predominant in secretory cells

Lysosomes and peroxisomes - answercellular digestion

cytoskeleton - answerfilaments and microtubules maintain cell shape; permit movement

types of injurious stimuli (cellular) - answerhypoxia, chemical/toxic agents, physical
agents, microorganisms and immunologic reactions, genetic defects, nutritional
imbalances

how does hypoxia affect cells? - answercauses cellular swelling, local or generalized
release of lactic acid

how do chemical/toxic agents affect cells? - answerdamage cell membrane

types of adaptive immunity - answerhumoral, cell-mediated

humoral immunity - answerutilizes circulating antibodies produced by B-lymphocytes

, primary response of humoral immunity - answer(1) antigen phagocytosed by
macrophage, (2) antigen presenting cells, (3) antigen delivered to B cells, (4) B cells
enlarge and differentiate into: antibody producing plasma cells, memory B cells

secondary response of humoral immunity - answermemory B cells respond to
subsequent antigen exposure in a more rapid and powerful way

cell-mediated immunity - answerexposure to antigen presented by macrophages cause
antigen-specific T-cell differentiation and proliferation in the lymphoid tissue; activated
T-cells continually cycle from lymph to blood to lymph, able to directly respond to an
antigen and destroy the target cell

where do B lymphocytes mature? - answerbone marrow

where to T lymphocytes mature? - answerthymus

what are the major components of innate immunity? - answerepithelial barriers,
phagocytic cells (neutrophils, macrophages), NK cells, plasma proteins, inflammatory
response

natural killer (NK) cells - answerT-cells; play role in both adaptive and innate immunity;
identify viruses, infections (non-self cells)

complement system - answeramplifies the antigen-antibody reaction; includes 9
interacting components (proteins); effects include: opsonization, agglutination,
neutralization, chemotaxis, mast cell and basophil activation, general inflammatory
effects

basophils - answerinnate immunity; release histamine

mast cells - answersecrete histamine; prompted to degranulate during activation

macrophages - answer"pac man"; consume bacteria, cell debris/waste; serve as APCs

neutrophils - answerrelease interleukins (cytokines) to signal other immune cells to
travel to injured area during chemotaxis

toll-like receptors - answersense damage; release chemical mediators that initiate
inflammatory response; found particularly in endothelial layer of capillary beds

antigen-presenting cells (APCs) - answerinclude macrophages, dendritic cells,
Langerhans cells, activated B-cells; (1) engulf foreign particles, (2) present fragment of
antigens on their own surfaces to be recognized by T cells

T cells - answerresponse to intracellular pathogens; recognize self
