capillaries
vessels
trunks
ducts
back into blood stream

Question 3

what are the regions of a lymph node and what cells are in each

Answer 3

inner cortex - T cells
outer cortex - B cells
medulla - B cells

Question 4

what are lacteals

Answer 4

specialized lymph nodes that transport/absorb fat in the GI

Question 5

what trunk drains the lungs

Answer 5

bronchomediastinal

Question 6

what is the cell called that can differentiate into any kind of cell and where is it produced

Answer 6

pluripotent

red bone marrow

Question 7

what cells live inside a lymph node

Answer 7

macrophages
B & T cells

Question 8

stages of inflammation and what is happening in each

Answer 8

vasodilation - arteries widen allowing increased blood flow, removes toxins, swelling, redness, heat

emigration - neutrophils accumulate to destroy microbes by phagocytosis, monocytes arrive

tissue repair - phagocytes carry out clean up, proliferation and remodeling begin

Answer 12

B cells/ plasma cells

Question 13

where are T cells born and where do they mature

Answer 13

born - red bone marrow
mature = thymus

macrophages
B cell
dendritic

Question 15

5 steps of phagocytosis

Answer 15

chemotaxis
adherence
ingestion
digestion
death

Question 16

how do natural killer cells kill stuff

Answer 16

granulosin
perforins
granzymes

Question 17

functions of major histocompatibility complex

Answer 17

identifies each cell in the body where it is foreign or not

MHC 1 - inside cell plasma membranes

MCH II - outside of cell - built into antigen presenting cell

Question 18

what is structural about lymphatic capillaries

Answer 18

anchoring filaments, more permeable, larger than blood capillaries

Question 19

difference between right and left lymphatic ducts

Answer 19

right drains the right side of head and upper body

left drains the rest of the body

cisterna chyli

Answer 20

where left thoracic duct originates

Question 21

what kind of capillaries exist in red bone marrow

Answer 21

highly vascularized sinusoidal

Answer 23

afferent
subcapsular
trabecular
medullary
efferent
hilum

Question 24

what happens in red and white pulp in spleen

Answer 24

red = cells go to die, platelet storage

white = immune response carried out by B & T cells

where is MALT found and what does it stand for

Answer 25

mucosa associated lymphatic tissue GI tract, renal, urinary tract

Question 26

second line defence

Answer 26

antimicrobial fever inflammation

Question 27

function of MCH

Answer 27

place markers or flags on plasma membranes

Question 28

MHC I

Answer 28

built into plasma membranes of all cells except RBC INSIDE CELLS
