- tonsils
- adenoids
- spleen
- thymus

- intestinal payers patch
lymphocytes b

lymphocytes t
born in the bone but matured in the thymus
what is the cause of an auto immune disease
loss of memory in the cells
B memory
remembers the enemy and lasts a few weeks to months
B plasmatic
produce antibodies (Ab) or immunoglobulin (Ig) and mark for destruction
what are the two local messengers
- leukotriene
- prostaglandins
order or deployment within WC when killing bacteria
- neutrophils
- basophils / eosinophils
- monocyte
- macrophage
order of lymphocyte t
t helper
t killer
t memory
t suppressor
active
attenuated virus (piece of the virus)
passive
antibody
how does streptococcus lead to kidney failure
bc of the toxins released from the streptococcus
virulance

gram -, e.coli
what is easier to kill gram - or +
gram -
order or lines of defense
- skin
- WC
- lymphocytes
what has no specific and kills everything
1st and 2nd line of defense (skin and WC )
what has a specific and is based on antibodies
3rd line of defense (lymphocytes )
interferon
connection between WC (interferes with the growth of bacteria or virus)
interleukin
communicates with T helper and the rest of the cells (texter)
fever
stimulates phagocytosis and causes vasodilation bringing in more macrophage
what are antigens
bacteria
virus
protozoa
worms
fungus
