purpose of the immune system - ANS immunity is the protection from illness or disease

immunocompetence - ANS is the ability of individual cells to recognize a specific antigen by
binding to it

antigens - ANS proteins able to stimulate an immune response (pollen, virus, bacteria)

What are immune cells responsible for? - ANS differentiating b/t self and nonself cells

Human Leukocyte Antigens (HLAs) - ANS unique protein on the surface of cell membranes and
are specific to an individual ( ex - fingerprint)

identical siblings are the only things that have the same HLAs

self-tolerance - ANS lymphocytes unresponsive to own antigens

general organization of the immune system - ANS most cells come from bone marrow and
produce stem cells

WBCs provide immunity

Leukocytes provide protection through defense mechanisms

phagocytes - ANS White blood cells that attack invading pathogens

T-cells - ANS Cells created in the thymus that produce substances that attack infected cells in
the body.

B-cells - ANS a lymphocyte not processed by the thymus gland ( Bone marrow), and
responsible for producing antibodies.

processes necessary for immunity - ANS immunity needs inflammation, antibody-mediated
immunity and cell mediated immunity, full immunity requires the function and interaction of all
three process

three stages of the inflammatory process - ANS stage 1) vascular response

stage 2) cellular exudate

, stage 3) tissue repair/Replacement

Stage 1 Vascular response - ANS injured tissue, leukocytes, tissue mast cell secretes
histamine, serotonin and kinins constricting small veins and dilating arterioles causing redness,
warmth, and edema of tissue

Stage 2 Cellular exudate - ANS puss that forms inside and neutrophilia. dead white blood cells.
leaders = mast cells, baso cell

stage 3 tissue repair and replacement - ANS begins at time of injury

WBCs trigger new blood vessels growth and scar tissue formation

function is lost whenever scar tissue forms

types of antibody-mediated immunity - ANS antibody mediated immunity (humoral immunity)

acquired immunity

natural active immunity

artificial active immunity

passive immunity

artificial passive immunity

natural passive immunity

antibody mediated immunity - ANS an adaptive immunity where body learns to make an
adaptive response to invasion by organisms or foreign proteins

acquired immunity - ANS occurs either naturally or artificially and can be passive or active

natural active immunity - ANS occurs when an antigen enters body naturally w/o human
assistance and your body responds by actively making antibodies against that antigen (
influenza A virus)

artificial active immunity - ANS developed by vaccination or immunization ( used to prevent
serious and potentially deadly illness (tetanus, diphtheria, polio) lasts many years and requires
"boosting"

passive immunity - ANS occurs when antibodies against antigen are transferred to a human
after first being made in body of another human or animal
