all 5 lymph nodes

Answer 12

1 pharyngeal
2 palatine
2 lingual

Question 13

phases of phagocytosis

Answer 13

chemotaxis
adherence
ingestion
digestion
death

Question 14

chemotaxis

Answer 14

phagocytes attracted to area by chemicals released by microbe or damaged cells

Question 15

adherence

Answer 15

microbe attaches to phagocytes cell membrane

Question 16

ingestion

Answer 16

microbe goes into cell from pseudopods

Question 17

digestion

Answer 17

microbe merges with a lysosome with digestive enzymes that breakdown microbe wall

Question 18

death

Answer 18

digestive enzymes digest microbe and kill it

Question 19

stages of inflammation

Answer 19

1. vasodilation, increased permeability
2. emigration of phagocytes
3. tissue repair

Question 20

B cells born and mature in?

Answer 20

bone marrow

Question 21

T cells born and mature in?

Answer 21

born in bone marrow
mature in thymus

Question 22

adaptive immunity

Answer 22

-acquired over a lifetime
-cell mediated and antibody mediated immunity

Question 23

innate immunity

Answer 23

-present at birth, not specific, doesn’t adapt
-first and second line of defence

Question 24

first line of defence

Answer 24

-skin and mucous membrane
- epidermis
-mucous membranes
-hairs
-cilia
-fluids

Question 25

second line of defence

Answer 25

-internal antimicrobial substances -natural killer cells -phagocytes -inflammation -fever

Question 26

complement system

Answer 26

enhances immune response by using proteins to poke hole in cell membrane of microbe causing it to burst (releasing histamine). then promotes phagocytosis and contributes to inflammation

Question 27

antibody actions

Answer 27

-neutralize antigens -immobilize bacteria -agglutinating and precipitating agent -activates compliment system -enhancing phagocytes

Question 28

endogenous vs exogenous

Answer 28

endo: inside cell, make MHC I exo: Outside cell, make MHC II

Question 29

what is a lacteal

Answer 29

specialized lymphatic capillary in guts that absorbs fat

Question 30

primary lymphatic organs

Answer 30

stem cells divide/ differentiate in red bone marrow and thymus

Question 31

secondary lymphatic organs

Answer 31

immune response occurs in lymph nodes, spleen, lymphatic nodules

Question 32

thymus

Answer 32

located in mediastinum active in early childhood, atrophies and is mostly gone by adulthood

Question 33

cells in cortex

Answer 33

made of immature T cells, dendritic, epithelial cells. many T cells die here, macrophages clean up

Question 34

cells in medulla

Answer 34

made of immature T cells, epithelial, dendritic and macrophages

Question 35

outer cortex cells

Answer 35

B cells in lymphatic nodules

Question 36

inner cortex cells

Answer 36

T cells and dendritic

what is MALT

Answer 40

mucous associated lymphoid tissue

Question 41

first and second line of defence is part of innate immunity

Question 42

are lymph capillaries bigger than blood vessels

Answer 42

yes and more permeable

Question 43

mechanisms by which lymph gets into lymph vessels

Answer 43

-overlapping, crammed epithelial cells leak fluid and promote fluid entry. -anchoring filaments -more pressure on outside rather than in
