What is feedback?
Information from sensors that allows a control center to compare current conditions to a set of ideal values
What happens in a feedback loop?
information moves continuously among sensors, a control center, and a target
What do feedback loops do?
They regulate most functions in the body
What in negative feedback?
A control system that maintains homeostasis by counteracting, or reversing change to return conditions to their set points. They help keep the internal environment stable
What is positive feedback?
A control center that uses information from sensors to increase the rate of change away from the set points. It is important whenever rapid change is needed
