denaturing

42
Q

What is negative feedback?

A

body works to bring back to the norm

43
Q

What is positive feedback?

A

body works to increase differences from the norm

44
Q

What is the stimulus in feedback loops?

A

the thing that is changing that triggers the loop

45
Q

What is the sensor in feedback loops?

A

something in your body that senses the deviation

46
Q

What is the integrating center in feedback loops?

A

something that compares the deviation to the normal

47
Q

What is the effector in feedback loops?

A

something that takes actions to bring the normal back

48
Q

What is the response?

A

the outcome because of the actions taken by the effector
