Final 4.1

Question 1

What does the lymphatic system contain

Answer 1

Lymph (liquid portion)
Lymphatic vessel
Nodes, tonsils, spleen, thymus, bone marrow

Question 2

What does immunity control

Answer 2

The ability to resist infection from disease

Question 3

What does a lymph do?

Answer 3

Acts as a second draining system

Question 4

What does the lymphedema contain

Answer 4

• blockage of lymph duct
• causes interstitial fluid accumulation
• edema and distinction of tissue
• infection risk increase in area
• elephantiasis

Question 5

What are elephantiasis

Answer 5

• caused by parasite attacking lymph vessels

- marked swelling, skin thickening

Question 6

What happens if fluids do not drain properly?

Answer 6

Causes lymphedema or swelling

Question 7

Where are the largest nodes?

Answer 7

Groin, axillae, neck

Question 8

What usually happening during infection

Answer 8

Swelling

Question 9

What are characteristics of lymph nodes

Answer 9

• Small lymph organs
• filter lymph before returning fluid to vena cava
• fixed macrophages “big eaters” eat debris and pathogens in lymph fluid
• first step in activating immune system

Question 10

What does the thymus do

Answer 10

• produces hormones to help mature lymphocytes( T-cells)

- peak in site/ function at 12

Question 11

What does the spleen do

Answer 11

• function like nodes but filters blood(not lymph)
• RBC graveyard
• tears easy/splenectomy common

Question 12

What are the large lymphoid nodules

Answer 12

Tonsils
Peyers patches
Appendix

Question 13

What is are peyers patches

Answer 13

Lymph tissue in digestive system

Question 14

Where the appendix located

Answer 14

Located along digestive/respiratory/urinary and reproductive tracts (open system)

Question 15

What’s another term for WBC

Answer 15

Leukocyte a

Question 16

What’s the way to remember the 5 types of leukocytes

Answer 16

Never Let Monkeys Eat Bananas

Question 17

What are the 5 types of leukocytes and where do they come from

Answer 17

Neutrophil
Lymphocytes
Monocytes
Eosinophil
Basophils 

Come from bone marrow

Question 18

What are the 3 classes of lymphocytes

Answer 18

• T-cells; mature in thymus
• B-cells; mature in bone marrow(make antibodies )
• NK (natural killer); float in blood

Question 19

What are the types of immunity

Answer 19

Inmate (born with it)

Adaptive

Question 20

What are the characteristics of inmate

Answer 20

-Contains and destroys invaders (7 methods)
Barriers, eating, poke holes, call for back up, turn up the heat
-Genetically determined, same response every time

Question 21

What’s the characteristics of adaptive immunity

Answer 21

• T & B cells
• what doesn’t kill you makes you stronger
  - T-cells specifically target bacteria and virus
  - B-cells produce new antibodies for every infection/vaccine
  - Never can get the same “cold” twice

Question 22

What is the lymphatic system responsible for?

Answer 22

For defending pathogens

Question 23

What is MCH

Answer 23

Protein which displays antigens like a flag on plasma membrane

Question 24

T-cells kill MCH type 1 or type 2

Answer 24

They kill MCH 1 but not MCH 2

Question 25

What does MCH consist of

Answer 25

• found on every cell (your cells and pathogens bacteria viruses)
• normally displays “self” antigens
• when infected YOUR cells displays foreign antigens instead of own

Question 26

What does MCH type 2 consist of

Answer 26

• present antigens of forefinger cells (bacteria or virus)
• signals “kill other cells that have this antigen”
• ONLY ANTIGEN PRESENTING CELLS HAVE MCH 2

Question 27

What are the two types of antigen presenting cells

Answer 27

Monocytes (big cells)

Marcophages (big eaters)

Question 28

How does B-cells and antibodies work?

Answer 28

-chemical attack on bacteria and virus
-antibodies bind to antigens and destroy cells
•very specific
•only ONE antibody/ B-cell

Question 29

B-cells use MCH 1 or MCH ?

Answer 29

MCH 2

Question 30

What happens to B-cells that are not used

Answer 30

They turn into memory B-cells which are saved for the next infection

Question 31

How long does it take for a vaccine to work?

Answer 31

• It takes 1-2 wks for the antibody method of immunity to work the first time (primary response )
• secondary response is much larger and faster b/c of saved memory B-cells
