Q

What is Feedback?

A

Your body systems work together to ensure that homeostasis is maintained, even when your body is “off balance”.

This is done through a system of feedback loops present in your body.

23
Q

Positive Feedback

A

Less common

Respond to change by amplifying that change.

Used to push processes to completion.

Ex. Childbirth

24
Q

Negative Feedback

A

Respond to change by opposing that change.
