Put simply, negative feedback is the process by which a change is detected and then an action occurs to neutralise the change, i.e. negatively affect the change.
For example, if blood glucose receptors measure a high amount of glucose in the blood, the the beta cells of the islets of langahans secrete insulin which increases glucose uptake and jump starts glycogenesis, ultimately decreasing the blood glucose levels.

What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback
What hormone works as a negative feedback to aldosterone?
Atrial natriuretic peptide.
How does a negative feedback system work and Explain how negative feedback regulates the amount of thyroxine in the blood?
When the amount of a particular hormone in the blood is reaches a certain level, the endocrine system sends signals to stop the release of that hormone. "Pearson Education Inc."
Regulating the hormone levels in the blood is it positive or negative feedback?
When the level of the particular hormone increases, the stimulating hormone level deceases and vice verse is there. So for example, when the level of the thyroid hormone increases, the level of the thyroid stimulating hormone decreases and vise verse. This is called as negative feed back system. This is how the negative feed back system works. In this type of regulation, you have a particular level of the hormone is set to have a desired level of the hormone, in your body. Some times this setting is changed. So you may have low level of the thyroid hormone or high level of the thyroid hormone is set, at your hand. This is probably done, some times, under the supervision of the higher centre called as hypothalamus. Hypothalamus is situated at the base of your brain. From hypothalamus, you get the releasing factors. In this case, the thyroid releasing factor. Many such factors regulate the 'setting' of hormone levels of your body. But again, this hypothalamus is not the 'ultimate' centre of regulation. Overall brain has direct or indirect effect on the hypothalamus. Your brain is not again the 'ultimate' centre of regulation. The brain is affected by genetic influence and have impact of the surrounding events on the same. All this is necessary for proper control of your homeostasis. Otherwise the thyroid could have secreted the hormone at particular pace regardless of any necessary control, for example.
What are the 4 conditions of homeostasis?
Four things that need to be maintained for homeostasis in the body is internal regulation, the ability to regulate pH. levels, regulation of blood pressure and regulation of glucose levels. Homeostasis overall is the balance of things that makes an organism well.
What is negative feedback in your bodies?
Self-regulating system; information about effect of hormone that is fed back to gland, which then decreases secretion of that hormone; most common method of regulation
What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback
How does negative feedback control hormone levels?
you grow
What hormone works as a negative feedback to aldosterone?
Atrial natriuretic peptide.
What usually regulates hormone concentrations in the blood?
Negative feedback usually regulates hormone concentrations in the blood.
How does the endocrines system's negative feedback system work?
Through negative feedback when the amount of a particular hormone in he blood reaches a certain level the endocrine system sends signals that stop the release of hormone.
How are hormone levels monitored and controlled?
Controlled largley by negative feedback, when hormone levels rise, signals are transmitted to the endocrine organ, releasing the hormone, telling the organ to decrease the amount of hormone released.
Are hormone concentrations usually controlled by positive feed back?
no by negative feedback
How does the endocrine system know when to stop releasing a particular hormone?
negative feedback
What is an example of how negative feedback controls the body's horemone levels?
Negative feedback is a process in which the body's hormones regulate and maintain homeostasis, or a state of equilibrium. This process is used to maintain stable internal conditions within the body, such as temperature, water balance, blood sugar levels, and hormone levels. Negative feedback occurs when hormones are released into the bloodstream, which then triggers an opposite response from the body to counteract the initial action. This is an example of how negative feedback controls the body's hormone levels. For example, when a hormone is released into the bloodstream, it can trigger the release of a second hormone that will inhibit or reduce the production of the first hormone. This is an example of negative feedback, as the second hormone acts as an inhibitor to the first hormone, which helps to maintain balanced hormone levels in the body. Additionally, some hormones can act as stimulators, meaning they can increase the production of another hormone, which will then reduce its own production. This is another example of negative feedback, as the stimulus hormone is stimulating the production of another hormone, which then helps to reduce its own production. In order to maintain a state of equilibrium, the body needs to be able to identify when the hormone levels are too high or too low and respond accordingly. Hormones can be regulated through a variety of mechanisms, including negative feedback, which is one of the most important ways in which the body regulates its hormone levels. Negative feedback helps to ensure that the body's hormones are kept in balance, which helps to maintain homeostasis.
Negative feedback means that when a hormone reaches a certain level the glands secretion is?
inhibited
What are most hormone action regulated by?
The hypothalamus regulates the Pituitary gland, and the Pituitary gland regulates the rest of the endocrine system.
