4 functions of n-s immune system
|
1. Defense against disease organisms
2. ID and destruction of abnormal cells 3. Repair of injury (cut) 4. Removal of senescent cells (worn out blooo cells) |
|
4 complications of the immune system
|
1. autoimmune diseases (starts killing normal cells)
2. excess reactions (n-s) 3. allergic reaction (spec) 4. graft rejection (kills new cells or organisms) |

erythrocytes
|
red blood cells, not directly involved---all the same
|
|
leukocytes (white blood cells)
|
white blood cells, lots of them and big.

|
|
barriers
|

|
|
physiological barrier
|
temperature
|
|

|
-activated by macrophages (in BOTH b/c they're the link to both systems)
-releases active chemicals (interleukins) |
|
interleukin
|
induce fever and alert spec. immunity.
-fever is good b.c it keeps bacteria from dividing. -releases CRF |
|
interferon
|
goes to cells in the area of infected cell to alert them to kill it
|
|
complement
|
punches holes in infected cells, plasma proteins, in plasma blood all the time
|
|
natural killer cells
|
attack tumor cells, if cell does not have correct receptor
