Immune Response

Question 1

Body’s reaction spec. the immune system when a foreign agent enters the body

Answer 1

IMMUNE RESPONSE

Question 2

Factors Affecting Immune Response:

Answer 2

OACG
OVERALL HEALTH STATUS OF INDIVIDUAL
AGE
CONCENTRATION & ROUTE OF ADMINISTRATION OF ANTIGEN TO THE HOST’S BODY
GENETIC CONTROL OF IMMUNE RESPONSE

Question 3

Healthy - ___
Weak / Poor - ___

Answer 3

FAST IMMUNE RESPONSE BC IMMUNE CELLS MORE ACTIVE
DEFICIENT / SLOW IMMUNE RESPONSE

Question 4

Neonatal / Newborns - ___
Geriatrics / Old Patients - ___

Answer 4

IMMUNE SYSTEM STILL DEVELOPING
WEAK IMMUNE SYSTEM –> SLOW IMMUNE RESPONSE

Question 5

Greater antigen administered = __

Answer 5

FASTER & GREATER IMMUNE RESPONSE

Question 6

Helps immune cells determine self from non-self

Answer 6

MHC (MAJOR HISTOCOMPATIBILITY COMPLEX)

Question 7

Occurs in 4 phases after exposure to an antigen

Answer 7

PRIMARY IMMUNE RESPONSE

Question 8

No antibody is detectable
Immune system process foreign antigens that enter the body

Answer 8

LAG PHASE

Question 9

Antibody titer increasing logarithmically / spiked

Answer 9

LOG / EXPONENTIAL PHASE

Question 10

Antibody titer stabilizes
Stationary / stable → equilibrium between antibody production and catabolism

Answer 10

PLATEAU PHASE

Question 11

Antibody titer decreases / catabolized → catabolism > production

Answer 11

DECLINE PHASE

Question 12

Elicited by a second by any subsequent exposure to the same antigen

Answer 12

SECONDARY IMMUNE RESPONSE / ANAMNESTIC / MEMORY RESPONSE

Question 13

Makes it possible for a more rapid Ab response, shorter processing period / Lag phase

Answer 13

MEMORY

Question 14

Predominant Ab in secondary immune response

Answer 14

IgG

Question 15

Lag Phase:
Primary - ___
Secondary - ___

Answer 15

LONGER
SHORTER

Question 16

Plateau Phase:
Primary - ___
Secondary - ___

Answer 16

SHORTER
LONGER

Question 17

Decline Phase:

Secondary - ___

Answer 17

LESS GRADUAL
MORE GRADUAL

Question 18

Answer 18

IgM

Question 19

AB Titer:
Primary - ___
Secondary - ___

Answer 19

LOWER
HIGHER
