Test 4- Lymphatic and Immune Systems

Question 1

Rapid response immunity

Answer 1

Innate immune defenses

Question 2

Adaptive immune defenses

Answer 2

Slow responses

Question 3

Includes the skin, mucous membranes, phagocytotic cells and antimicrobial proteins

Answer 3

Innate defenses

Question 4

What is the sequence of innate immunity

Answer 4

• entry of microbe
• vasodilation of infected area
• increased capillary permeability
• leukocyte invasion
• destroy microbe
• tissue repair

Question 5

What is the inflammatory response

Answer 5

• damaged cells release chemicals that induce blood vessels to dilate
• local clotting reactions seal off infected region
• WBC’s disinfect and clean area

Contains high concentration of lymphocytes

Answer 12

tonsils

Question 13

What are the 2 types of adaptive immunity

Answer 13

active immunity

passive immunity

Question 14

Achieved by expose to invader , when B lymphocytes respond and attach to the pathogen and memory cells are formed

Answer 14

Active immunity (vaccines)

Question 15

Achieved when the person receives the antibodies from someone else (placenta, breastmilk)

Answer 15

Passive immunity

Question 16

Make antibodies that bind to specific antigens

Answer 16

B lymphocytes

Question 17

Answer 17

T kymphocytes

Question 18

Immune system turns against its own body cells

Answer 18

Autoimmune diseases

Question 19

Part of all of the immune system is lacking

Answer 19

Immunodeficiency

Question 20

Inherited disorder in which both T cells and B cells are absent or inactive

Answer 20

SCID (severe combines immunodeficiency)

Question 21

Virus kills T cells, weakening the immune system and making individual more prone to illinesses

Answer 21

HIV

Question 22

Allergic reaction stages

Answer 22

Sensitization

Second exposure

Question 23

Person is first exposed to allergen eliciting B cells to form a clone of the allergen and the antibodies produced trigger an inflammatory response

Answer 23

Sensitization

Question 24

Antibodies bind to the allergen and release histamine in greater amounts than in formation inflammatory response

Answer 24

Second exposure
