What is aldosterone hormone?
Aldosterone is a hormone that is produced by the adrenal glands. It works primarily on kidney (renal) cells to help maintain the balance of fluids and electrolytes in our bodies. Its mainly works to control reabsorption of sodium and chloride and secretion of potassium and hydrogen. If aldosterone production is not functioning properly, there can be serious consequences to the heart, kidneys and electrolyte balance.
How does a negative feedback system work and Explain how negative feedback regulates the amount of thyroxine in the blood?
A negative feedback system works by detecting changes in a physiological variable and activating mechanisms to counteract those changes, maintaining homeostasis. In the case of regulating thyroxine levels in the blood, if the concentration of thyroxine becomes too high, the hypothalamus reduces the release of thyrotropin-releasing hormone (TRH), which in turn decreases the secretion of thyroid-stimulating hormone (TSH) from the pituitary gland. This leads to a decrease in thyroid hormone production by the thyroid gland, helping to restore normal thyroxine levels in the blood.
What is the difference between feedback negative feedback a negative feedback response a negative feedback mechanism and a negative feed back loop?
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
Regulating the hormone levels in the blood is it positive or negative feedback?
Regulating hormone levels in the blood typically involves negative feedback mechanisms. This means that when hormone levels reach a certain threshold, a signal is sent to stop the production or release of that hormone, helping to maintain homeostasis in the body.
Which part of the nephron is under the control of the hormones ADH and aldosterone?
The distal tubule and collecting duct are the parts of the nephron that are under the control of the hormones ADH (antidiuretic hormone) and aldosterone. These hormones regulate water reabsorption and sodium reabsorption, respectively, in these segments of the nephron.

How does negative feedback work?
To remove the distortion ... ANSWER: It does not reduce distortion but rather make the circuit stable. There can be distortion even with negative feedback by bad design in other word feedback does not reduce distortion.

What is a disorder caused by deficiency of aldostone?
Addison's disease and Congenital adrenal hyperplasia are the names of disorders associated with a deficiency of aldosterone, both are rare. Aldosterone is a hormone secreted by glands that sit on top of the kidneys (adrenal glands). This hormone basically works on how our bodies hold on to the salt and water content of our blood, which affects our blood pressure. It also works to allow our bodies to release potassium.

How does a negative feedback system works?
it compares the output with the input and adjusts it self to match with it.
What roles does estrogen play in the in the feedback mechanism?
Gonadotropin-releasing hormone (GnRH) is a neurohormone secreted by the preoptic nuclei of the hypothalamus. This hormone causes leuteinizing hormone to be released by the anterior pituitary. LH works its way through the bloodstream to the ovaries, which produce estrogen. Estrogen has a feedback loop with both the hypothalamus and the anterior pituitary. Whether the mechanism is positive or negative depends. In ovulation, this mechanism is positive, so high estrogen levels will induce even higher LH levels.
Regulating the hormone levels in the blood is it positive or negative feedback?
Regulating hormone levels in the blood typically involves negative feedback mechanisms. This means that when hormone levels reach a certain threshold, a signal is sent to stop the production or release of that hormone, helping to maintain homeostasis in the body.

What is the negative feedback loop in science?
Negative feedback is a process that happens when your systems need to slow down or completely stop a process that is happening. When you eat, food travels into your stomach, and digestion begins. You don't need your stomach working if you aren't eating. The digestive system works with a series of hormones and nervous impulses to stop and start the secretion of acids in your stomach. Another example of negative feedback occurs when your body's temperature begins to rise and a negative feedback response works to counteract and stop the rise in temperature. Sweating is a good example of negative feedback.
What regulates water reabsorption in the distal convoluted tubules?
The hormone aldosterone regulates water reabsorption in the distal convoluted tubules. It works by increasing the reabsorption of sodium ions, which in turn triggers the reabsorption of water from the tubules back into the bloodstream.
What is the main characteristic that demonstrates a negative feedback?
The main characteristic of negative feedback is that it works to counteract or reduce a change in a system, maintaining balance or stability. It acts to reverse the direction of the change, helping to regulate and maintain homeostasis.
