Question 1

Native or natural immunity that gets rid of harmful organisms

Answer 1

Innate

Question 2

Occurs after tissue injury or invasion of organisms

Inflammations does not always mean this

Answer 2

Infection

Question 3

Protection from invaders by phagocytosis

Anc

Answer 3

Neutrophils

Absolute nutraphil count = number of nature nutraphil count

Question 4

Liver, spleen and intestinal tract has a high number

Very good at phagocytosis large cells long life

Answer 4

Macrophages

Question 5

Stimulate inflammation

Answer 5

Basophils

Question 6

Limits inflammatory response increases during allergic response

Answer 6

Eosinophils

Question 7

Maintain and prolong inflammation and allergic reactions

Answer 7

Tissue mast cell

Question 8

5 cardinal signs of inflammation

Answer 8

Warmth 
Redness
Swelling 
Pain 
Decreased function

Question 9

Sequence of inflammatory responses

Answer 9

Stage 1- changes in blood vessels

Stage 2- neutrophils, pus

Stage 3- tissue repair replacement - WBC trigger new blood vessel growth and scar tissue formation

Question 10

immunity that develops after exposure to a suitable agent (as by an attack of a disease or by injection of antigens) — compare active immunity

Answer 10

Acquired immunity

Question 11

Body learns to make adaptive response

Answer 11

Natural active immunity

Question 12

Vaccines

Must be exposed to a dose to stimulate immune response

Answer 12

Artificial active immunity

Question 13

Antibodies are passed to human after being made in another human or animal

Answer 13

Passive immunity

Question 14

Cell-mediated immunity is an immune response that does not involve antibodies. Rather, cell mediated immunity is the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to antigen.

Answer 14

CMI

-t cells

Question 15

Transplant rejection

Begins immediately; results of antigen - antibody complexes that form in the blood

Widespread clotting leads to vessel necrosis

Organ must be removed immediately

Answer 15

Hyperacute rejection

Question 16

Transplant rejection

Begins 1 week - 3 mos; inflammatory response causes lysis of organ cells

Immunosuppressants to try to salvage organ

Answer 16

Acute rejection

Question 17

Transplant rejection

Happens over time with all solid organ transplants

Due to chronic infection inflammation and scarring

Controlling the immune response can delay

Answer 17

Chronic rejection

Question 18

Transplant rejection

Immunosuppressants

Corticosteroids and antiproliferative agent said

Answer 18

Maintenance therapy

Question 19

Transplant rejection

Used to treat acute episodes

Same drugs as maintenance but higher doses

Answer 19

Rescue therapy

Question 20

Protect body from effects of invasion by organisms

Inflammation, antibody mediated immunity, and cell mediated immunity are needed

Answer 20

Leukocytes (WBCs)

Question 21

Changes in immune function related to aging

Answer 21

Decreased activity of neutrophils

Less antibody response to antigens

Less T-lymphocytes (weakened immune system)
