19
Q

homeostasis

A

maintenance of relatively constant internal environment within the body

20
Q

True or false: the body can fluctuate in values

A

true

21
Q

variables are_____

A

conditions

22
Q

Normal range

A

the range of the homeostatic values of variables

23
Q

set point

A

ideal normal value of a variable

24
Q

Negative feedback

A

counteracts change in variable
regulates the body systems

25
Q

What are the three components of negative feedback?

A

receptor, control center, effector

26
Q

receptor

A

monitors the value of some variable

27
Q

control center

A

establishes the set point

28
Q

effector

A

change the value of the variable, usually the organ

29
Q

stimulus

A

deviation from the set point that is detected by the receptor

30
Q

Positive feedback

A

response makes the detected deviation greater
