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.

When the body changes an internal condition back to it's normal state it is called feedback?

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 is when the body reacts in the same direction as a stimulus. Negative Positive?

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.


Compare and contrast negative and positive feedback mechanisms and give some examples?

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.

What is the difference between positive feedback and negative feedback?

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.

Are positive feedback and negative feedback both components of homeostasis?

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?

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.
