Q

ability to maintain balance despite changes in internal and external changes

A

homeostasis

20
Q

is termed a controlled condition

A

feedback loop

21
Q

any disruption that causes a change in a controlled condition is called a

A

stimulus

22
Q

3 other components of feedback systems

A

receptor, control center, effector

23
Q

homeostasis is maintained by

A

feedback systems

24
Q

monitors the controlled condition and sends info to a control center

A

receptor

25
Q

receives the input, compares it to a set of values that the controlled condition should have

A

control center

26
Q

receives output commands and produces a response that changes the controlled condition

A

effector

27
Q

a feedback system reverses and change the controlled condition to restore to set point

A

negative feedback system

28
Q

if a feedback system further strengthens a change in the controlled condition

A

positive feedback system

29
Q

descriptions of any part of the human body assume that the body is in a specific stance
