immune system infection diseases

Question 1

what is an antigen

Answer 1

protein component of pathogen that elicits the immune response

Question 2

what are specialized cells

Answer 2

lymphocytes and phagocytes for response to a foreign substance

Question 3

what are antibodies or immunoglobulins

Answer 3

proteins that destroy antigens

Question 4

what are biological factors causing immune response

Answer 4

foreign substance or pathogen

Question 5

how do PTs treat infection diseases

Answer 5

treat s/sx of infection and timing of infection

Question 6

what does the immune system do

Answer 6

protects “self” from “nonself” which is necessary for survival

Question 7

what does non self refer to

Answer 7

external or internal

Question 8

what does self refer to

Answer 8

autoimmune response

Question 9

what role do tissue and organs play in immune response

Answer 9

recognition and elimination of foreign pathogen

Question 10

immune system dysfunction leads to

Answer 10

illness and disease  varying physiologic change, clinical expression, and FUNCTIONAL DEFICITS  severity

Question 11

what does antigen specific mean

Answer 11

adaptive

Question 11

what does nonspecific mean

Answer 11

innate

Question 11

non specific immunity characteristics

Answer 11

response is antigen independent
there is immediates maximal response
not antigen specific
exposure results in no immunologic memory

Question 12

specific immunity characteristics

Answer 12

response is antigen dependent
there is a lag time between exposure and maximal response
antigen specific
exposure results in immunologic memory

Question 13

adaptive immunity or antigent specific response can be further broken down into humoral which is

Answer 13

antibody mediated = B cells

Question 14

adaptive immunity can be further broken down into cell mediated which consists of

Answer 14

T cells

Question 15

humoral means

Answer 15

B cells have been triggered to produce antibodies

Question 15

cell mediated means

Answer 15

cell communicates with/triggers cell, no antibody

Question 16

cells of the immune system

Answer 16

monocytes
lymphocytes
granulocytic cells (neutrophils, basophils)

Question 17

innate immune system cells

Answer 17

macrophage (primary WBC)
neutrophil
basophil
dendritic
natural killer
T cell

Question 18

adaptive immunity cells

Answer 18

B cell
T cell

Question 19

adaptive response immunity

Answer 19

Antibody-Mediated & Cell-Mediated: provides specificity and memory of previous antigen encounters (vaccinations

Question 20

innate response immunity

Answer 20

generalized immune response includes epithelial barriers, mucociliary clearance, phagocytic cells, and complement proteins present antigens to antigen specific immune response

Question 21

monocytes

Answer 21

circulate in the blood

Question 22

macrophage

Answer 22

present in tissue

Question 23

lymphoid organs

Answer 23

Macrophage (innate) present antigens to T lymphocytes (adaptive)

Question 24

Monocytes and Macrophages contain receptors that facilitate their action in the nonspecific pathway engulf and destroy a pathogen and antigen-specific pathway: trigger T cells

Answer 24

Present the foreign material antigen to T lymphocytes
-T cells trigger the release of cytokines
- Cytokine release causes B lymphocytes to produce antibodies
- Antibody molecules released

Question 25

leukocytes (WBC) include following cells

Answer 25

lymphocytes (T and B)
granulocytes (eosinophils, basophils, neutrophils)
monocytes

Question 26

B lymphocutes

Answer 26

10-15%

Question 26

T lymphocytes

Answer 26

70-80% of blood lympocytes

Question 27

T cells mature in the

Answer 27

thymus

Question 27

mature T cells migrate to the

Answer 27

lymphoid tissues

Question 28

lymph fluid

Answer 28

collection of interstitial fluid by way of lymph capillaries, cleaned by lymphocytes in the lymph nodes

Question 29

T cells push and pull of pressure

Answer 29

T Cells recirculate between the blood and the lymph fluid via hydrostatic and osmotic pressures

Question 30

t lymphocytes

Answer 30

are bridge between innate and adaptive immunity
often called antigen speficic cell mediated
link between phagocutic activity and B cell activation
