Feedback systems maintain homeostasis in the body i.e. they keep our internal environment as constant as possible, minimising the effects of fluctuations in sugar levels and temperature, among many others.
positive feedback system
Positive feedback speeds up reactions while negative feedback slows them down. Positive feedback goes with the force that put the body out of homeostasis in order to get it over faster. For example, during childbirth, the body goes with it in order to get it over faster so that the body can return to homeostasis. On the other hand, negative feedback opposes the action. For example if your body temperature drops, your receptors in your body send a message to your brain to tell it your cold. Your brain then sends a message to your muscles to shiver to help warm you up.
Positive and negative feedback
A positive feedback loop can disrupt a system in homeostasis by amplifying an initial change away from the set point, leading to an escalation of the deviation. This can push the system further out of balance and prevent it from returning to its original state. In extreme cases, a positive feedback loop can result in system failure or collapse.
This process is called negative feedback. There are only two that are positive: childbirth and blood clotting. Negative feedback keeps things in balance.
positive feedback system
Feedback control is the process by which a system's output is monitored and used to adjust the system's input. This mechanism allows the body to regulate internal conditions within a narrow range, maintaining homeostasis. Negative feedback is a common type of control system where the system responds in a way that reduces the discrepancy between the desired and actual output.
Feedback can be both negative and positive. Negative feedback occurs when the body's response counteracts the stimulus, helping to maintain homeostasis. Positive feedback amplifies the stimulus, leading to a larger response.
Negative feedback mechanisms work to maintain homeostasis by reversing a change in a system, while positive feedback mechanisms amplify and reinforce a change. An example of negative feedback is the regulation of body temperature – if body temperature rises, mechanisms kick in to lower it; whereas in positive feedback, childbirth contractions become stronger and more frequent to facilitate delivery.

when a woman's contractions speed up during labor is negative or positive feedback
Yes, both positive and negative feedback are components of homeostasis. Negative feedback helps to maintain a stable internal environment by reversing any deviations from a set point, while positive feedback amplifies the response to a stimulus, often to achieve a specific outcome in the body. Both types of feedback work together to regulate physiological processes and maintain balance within the body.
If a change in the body causes more change in the same direction, the system is called positive feedback. This feedback loop amplifies the initial change and pushes the system further away from its original state.
