What is the endocrine definition of self-regulating?
The endocrine system has four major mechanisms of control that regulate its functions. They are: Hormonal control, neural control, negative feedback, and positive feedback.
What kind of negative loops are used to regulate chemical pathways?
Negative Feedback Loops
How does negative feedback help regulate your internal body temperature?
it helps your internal body temperature alot. The negative feedback heats the inside of you so you don't freeze. Its pretty simple when you think about it. Negative feedback is like a thermostat.
Explain how do feedback loops allow the body to maintain homeostasis?
They work a bit like a thermostat that keeps a constant temperature in a house. Negative feedback loops work through receptors, which sense a change such as in blood pressure. Signals are then sent to the control centres, usually in the brain, which then give instructions to the effectors - mechanisms which then regulate conditions such as blood pressure and bring it back to normal
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.
What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback

Do most hormones regulate by negative feedback mechanisms?
Yes and most biochemical path ways are regulated by negative feedback. Enough of the product made inhibits the enzyme, or biochemical pathway, from making more product/reactions.

How do target organs most often regulate the pituitary gland?
Negative feedback inhibition
How does negative feedback regulate the amount of thyroxine in the blood?
blood level gets low
What is An example of positive feedback is?
Positive feedback mechanisms are designed to accelerate or enhance the output created by a stimulus that has already been activated. Unlike negative feedback mechanisms that initiate to maintain or regulate physiological functions within a set and narrow range, the positive feedback mechanisms are designed to push levels out of normal ranges. To achieve this purpose, a series of events initiates a cascading process that builds to increase the effect of the stimulus. This process can be beneficial but is rarely used by the body due to risks of the acceleration's becoming uncontrollable. One positive feedback example event in the body is blood platelet accumulation, which, in turn, causes blood clotting in response to a break or tear in the lining of blood vessels. Another example is the release of oxytocin to intensify the contractions that take place during childbirth.
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 is the function of a feedback loop?
to regulate a process
What is meant by negative feed back related to homeostasis?
Negative feedback mechanisms work to self-regulate levels of certain substances within the body. Usually this occurs as a substance is produced when levels become too low, then as the levels begin to rise the substance being released inhibits its own production so that the levels do not get too high. For example when body temperature begins to rise the body will bring about a set of reactions (sweating etc) to put temperature back to normal when temperature is at normal levels negative feedback puts a stop to these reactions so that temperature does not then continue falling. Another negative feedback mechanism with hormones is where the substance the hormones control causes the negative feedback, e.g. when glucose levels are high insulin is released but when glucose levels are at normal levels the insulin is no longer produced.
