Immunity

Front 1

Function of the immune system

Back 1

1. provide contiuous surveillance
2. protect body from invading organisms
3. maintains homeostasis
4. discovers and siposes of abnormal cells

Front 2

main divisions of immune system

Back 2

1. central lymphoid organs [bone marrow, thymus]
2. peripheral lymphoid organs [lymph nodes, spleen, tonsils, adenoids,appendix]
3. specailized cells

Front 3

Protective surface phenomena

Back 3

first line of defense
skin, seromucous surfaces, respiratory system, GI system, urinary system

Front 4

General Host Defenses

Back 4

second line of defense
inflammation

Front 5

Specific Immune Response

Back 5

Third line of defense
humoral immunity, cell-mediated immunity

Front 6

IgG

Back 6

most abundant in blood.
crosses placental barrier and protects newborns for several months, provides most natural and acquired immunity

Front 7

IgA

Back 7

found in exocrine secretions [saliva, tears,breast milk], protects mucosal surfaces from invasion by pathogenic bacteria and viruses

Front 8

IgM

Back 8

responsible for primary immune response; forms antibodies to ABO blood antigens; stimulates complement system, leading to cell-mediated immunity

Front 9

IgE

Back 9

attaches to mast cells and basophils, triggers the release of histamine at the site and cause symptoms of allergic reactions, provides defense against parasite

Front 10

IgD

Back 10

found on the surface of B cells and helps regulate B cell function; important in antigen recognition

Front 11

S/S inflammation

Back 11

redness, swelling, heat, pain, loss of function

Front 12

S/S infection

Back 12

fever, rubor [redness], calor [heat around infection], dolor [pain], tumor [edema], function lasea [not being able to move it]

Front 13

glucocorticods affect the immune system

Back 13

suppress immune response, dealy wound healing, and increase susceptibility to infection

Front 14

nosocomial infection

Back 14

infection acquired in a hospital or other health care setting
