Homeostasis Flashcards
1
Q
homeostasis
A
the existence and maitenance of a relatively constant environment within the body
2
Q
variables
A
because their values can change– of this fluid must remain within a narrow range
3
Q
set point
A
an ideal normal value
4
Q
normal range
A
a range of values close to a set point which homeostasis is maintained in
5
Q
negative feedback
A
any deviation from the set point is made smaller or resisted
6
Q
receptor
A
monitors the value of a variable
7
Q
control center
A
recieves information about the variable from the receptor
8
Q
effector
A
produces the ersponses that change the value of the variable
9
Q
positive feedback
A
when a deviation from the nromal value occurs, the systems response is to make the deviation greater. usually leads away from homeostasis
