How are negative and positive feedback involved in homeostatic regulation?

Negative feedback occurs when the output of a system reacts to cancel out the effects of an input of a system, as opposed to positive feedback (in which the actions/output is intensified or increased). The more negative, the more stable. Thus, with things being canceled out, the body maintains homeostasis.
An example of negative feedback in action is the maintenance of blood glucose levels and body temperature. With input of sugar, insulin is released to stabilize the body (on the other hand, without insulin, Diabetes can be diagnosed). With a raise in body temperature, blood vessels and pores are opened to release heat.

∙ 14y agoIn positive feedback a change in the homeostatic condition is detected by receptors and the information is transmitted to the control centre. The control centre activates effectors which generate a responce which increases the stimulus further reinforcing the initial change. Therefore, positive feedback acts to reinforce or strengthen the stimulus or charge.

The endocrine system often uses negative feedback to maintain homeostasis.Through negative feedback, when the amount of a particular hormone in the blood reaches a certain level, the endocrine system sends signals that stop the release of that hormone.

Are positive feedback and negative feedback both components of homeostasis?
No, negative feedback is the primary homeostatic mechanism regulating the endocrine system. Positive feedback is used much less frequently.
What is homeostatic regulation?
Homeostatic regulation is controlled in the body by the autonomic nervous system and seeks to maintain relatively stable conditions in the internal environment. The main gland of homeostasis is the hypothalamus and the major organ of homeostasis are the kidneys.
Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state?
Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state stimulate changes to occur in the opposite direction.
What is a control mechanism that responds to a stimulus by decreasing its intensity called?
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.
Is respiration a negative feedback?
its a negative feedback because the rate is not changing
What is the Primary mechanism of homeostatic regulation?
The body's primary mechanism of homeostatic regulation is negative feedback. This mechanism recognizes the problem, identifies the correction, and changes the variable.

The homeostatic mechanism that is constantly fluctuating is called the what?
Negative Feedback
Why is negative feedback valuable in metabolic processes?
Negative feedback loops primarily focus on maintaining the body's homeostatic functions.
Why negative feedback is essential to a homeostatic system?
Negative feedback loops are important because it helps the body return to homeostasis.
What is the effect of a negative feedback mechanism?
A negative feedback system is what occurs most commonly in your body systems. These keep everything in a homeostatic state.

Definition of negative feedback and positive feedback?
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state?
Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state stimulate changes to occur in the opposite direction.
What are four conditions in the cell that must be kept in the homeostatic balance?
- temperature - negative feedback loop - positive feedback loop - water balance
Mechanism that allows the body to change an internal condition back to normal?
Homeostatic mechanisms return the body to its normal state. Most of these are controlled by negative feedback.
