specialized
skin, bones, nerve cells |
|
|
reproduction
without reproduction of cells |
the formation of new cells or organisms
growth and development wouldn't be possible |

|
homeostasis
|
to stay the same ; constant
|
|
|
variable
ex |
conditions with value that can change
temp., chemical content |
|
|
set point
|
the ideal normal value.
|
|
|
most systems of the body are regulated by ?
|
negative feedback which maintain homeostasis
negative-good |
|
|
3 components of negative feed back
|
receptors (receivers)
control center effector (change) |
|
|
receptor
ex |
monitor the value of a variable.
blood pressure |
|
|
control center
|
establish the set point around which the variable is maintained
|
|
|
effector
|
can change the value of the variable. produce a response that return the variable to the set point
|
|
|
stimulus
|
a deviation from a set point
|
|
|
positive feedback
|
response is not homeostatic and a rare in health individuals
(bad) |
|
|
what is the negative effect of positive feed back
|
when a deviation from the normal value occurs the respose of the system is to make the deviation even greater
