Immune System Lab Quiz

Question 1

What are the two types of defense systems?

Answer 1

Innate

Adaptive

Question 2

What is part of the innate immune system?

Answer 2

Macrophage
Natural killer cell
Neutrophil

Question 3

What types of WBC’s are in the adaptive immune system?

Answer 3

B cell

T cell

Question 4

What is the 1st line of defense of the immune system?

Answer 4

• Innate
• External
• Skin
• Immediately engages with foreign objects using an arsenal of the stuff we were born with (physical chemical barriers)
• Natural external barricades deploy chemical defenses

Question 5

3 components of internal (2nd line of defense)

Answer 5

1. Neutrophils
2. Macrophages
3. Natural killer cells

Question 6

What does a penetrated barrier do?

Answer 6

release of phagocytic cells (WBCs from bone marrow)

Question 7

Neutrophils

Answer 7

devour and self-destruct

• Most abundant
• Easily identified following death (pus)

Question 8

Macrophages

Answer 8

• digest and spit out
• Tougher WBC (“big eater”)
• Act as a signaler via break and brag method
• ->Break invader, display remains on grooved proteins

Question 9

What do Natural Killer Cells do?

Answer 9

• Death poke (apoptosis)

- Patrol blood and lymph looking for abnormal cells

Question 10

What does barrier disruption cue?

Answer 10

inflammatory response

Question 11

Learned Immunity

Answer 11

Acquired through differentiating friend from foe

Question 12

Antigens

Answer 12

Large signaling molecules not normally found in the body

• -> found on the surfaces of pathogens from outside sources
• -> act as flags that rev up immune system

Question 13

Adaptive vs. Innate

Answer 13

Adaptive takes more time to recruit

• commits to memory
• specific threat detection
• Systemic action

Question 14

Systemic action

Answer 14

Humoral immunity –> B cells (antibodies

Cellular defenses –> T cells

Question 15

B cell

Answer 15

Lymphocyte produced and matured in bone marrow

Ability to remember friend from foe

Patrol body’s humors (blood and lymph) inactively until antigen comes along

Question 16

Immunocompetence

Answer 16

recognition and binding to a particular antigen

Question 17

Self-tolerance

Answer 17

learning to not attack own cells

Question 18

Organic pathogen introduction

Answer 18

• Pathogens from the environment

- Ready-made maternal antibodies via passive humoral immunity

Question 19

Artificial pathogen introduction

Answer 19

Pathogens from vaccinations

- introduce dead, weakened, or detoxified pathogens

Question 20

T cells

Answer 20

• Lymphocyte produced in bone marrow and matured in thymus

- Fight body cells that have been hijacked by viruses/bacteria

Question 21

Types of T cells

Answer 21

Helper T

Cytotoxic

Question 22

Helper T cell

Answer 22

Signaler

• Only binds to a specific antigen
• Activation –> multiplication –>alarm (cytokine release)

Question 23

Cytotoxic

Answer 23

Killer

• Look for infected cells via altered protein
• Binds and promotes apoptosis

Question 24

T cell function

Answer 24

• main regulator of immune response
• Stimulate inflammation
• Activate macrophages
• Fire up other T cells

Question 25

Globin

Answer 25

Protein

Question 26

Hem/ hemat

Answer 26

blood

Question 27

immun

Answer 27

exempt / immunity

Question 28

leuk

Answer 28

white

Question 29

lymph

Answer 29

clear water or fluid

Question 30

necr

Answer 30

death

Question 31

thromb

Answer 31

clot

Question 32

-emia

Answer 32

condition of blood

Question 33

-lysis

Answer 33

loosen or dissolve

Question 34

-oma

Answer 34

tumor

Question 35

-penia

Answer 35

abnormal reduction in number / deficiency
