Negative feedback mechanisms regulate?
the amount of blood sugar in the bloodstream
How does a negative feedback system work 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."

As thyroxine levels increase in the blood they exert negative feedback on the release of TSH by the pituitary gland. What effect will this have on the release of TSH?
As thyroxine levels increase the amount of TSH produced will decrease. On the other hand, when TSH levels increase the thyroxine levels will decrease. This is what causes the TSH/thyroxine levels to fluctuate.
Why you need negative feedback mechanism?
So you can regulate the amount of products produced. The negative feedback mechanism is where a product, or a product of a multi-step reaction, inhibits an enzyme or catalyst in an earlier step of the reaction to keep the concentration of product from exceeding maximal values.
What allows negative feedback to a control system?
the system has parts that sense the amount of output
What is an example of negative feedback?
An example of negative feedback would be a secretion of greater amount of insulin to lower the blood sugar level, and then secretion of greater amount of glucagon to increase the blood sugar level, and then a secretion of a greater amount of insulin to lower the blood sugar level..... etc.
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.
The water balance of the body is maintained bu negative feedback what does this mean?
Water balance refers to the amount of water gained and lost by the body.
What amount of thyroxine tablets should you take daily?
This is entirely dependent on what your FT4 and FT3 levels are. You need to get a prescription for blood tests and have them sent to an endocrinologist who will then be able to accurately prescribe the amount of thyroxine you should take.
What is a negative feedback regulation of a hormone?
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.
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.
