Negative feedback systems are processes that sense changes in the body and activate mechanisms that reverse the changes in order to restore conditions to their normal levels.
Glucose levels are regulated by hormones including insulin, glucagon, amylin, GLP-1, glucose-dependent insulinotropic peptide (GIP), epinephrine, cortisol, and growth hormone. Of these, insulin and amylin are derived from the beta-cells, glucagon from the alpha-cells of the pancreas, and GLP-1 and GIP from the L-cells of the intestine.

How does the feedback control system for insulin production work?
The control of blood glucose levels operates by what is known as a negative feedback mechanism. Here is a summary of the 2 control loops.When the blood glucose level goes upBlood sugar (glucose) rises;The pancreas detects the rise;The pancreas pumps out insulin into the blood;Insulin helps the uptake of glucose into muscles and other cells;This causes the blood glucose level to fall to its normal set point; andThe pancreas detects the fall and switches off insulin production.When the blood glucose level goes downBlood sugar (glucose) drops;The pancreas detects the drop in blood sugar;The pancreas switches on the output of glucagon into the blood;Glucagon signals the liver to break down glycogen into glucose;The liver releases glucose into the bloodstream;Blood glucose goes up to its normal set point; andThe pancreas detects the rise in blood sugar and switches off glucagon release.
What is it called when ions or molecules in the blood stimulate the release of a hormone?
i don't really know and sure but i think it is blood.
The blood platelets accumulation during blood clotting in response to any damage to the lining of the blood vessels is?
a negative feedback mechanism
What is antagonistic feedback system?
An antagonistic feedback system is a regulatory mechanism in which two components or processes work in opposite directions to maintain homeostasis. For example, in the regulation of blood glucose levels, insulin and glucagon act antagonistically to keep blood sugar within a normal range. These systems help prevent excesses or deficiencies in physiological processes.
What chemical is responsible for the decrease in blood glucose concentration is released by?
Insulin is the hormone responsible for decreasing blood glucose levels. It is released by the pancreas in response to high blood sugar levels, helping to regulate glucose in the body.
What hormone is involved in blood glucose regulation?
There are two hormones that regulate blood glucose levels. One is insulin. This horemone "carries" glucose into the cell. No glucose and the cell starves and the glucose levels get higher in the blood. The second hormone takes glucose out of liver storage and increases the glucose in the blood. These two are a feedback mechanism that keeps the levels in a normal range.
A decrease in blood glucose that causes the inhibition of insulin is an example of?
A decrease in blood glucose that causes the inhibition of insulin secretion is an example of a negative feedback mechanism. In this case, low blood glucose levels trigger the inhibition of insulin release to prevent further lowering of blood sugar and maintain homeostasis.
Negative feedback with increase in blood glucose?
negative feedback can increase the concentration of glucose in the blood stream. if the blood glucose levels are too low, alpha cells will produce glucagon which causes the liver to break glycogen down into glucose. it is then released into the blood stream which increase the blood glucose levels.if it is too high, the beta cells will produce insulin which causes the liver and muscle cells to form glycogen from glucose. In addition, other cells are encouraged to use glucose in cell respiration rather than fats.both the beta and alpha cells are produced from the pancreas.
What is the feedback mechanism of insulin?
An increase in blood sugar levels cause the release of the hormone insulin by the pancreas. Insulin then lowers this blood sugar level restoring it to original non-lethal blood glucose levels.
What is mechanism of CARP?
The mechanism of CARP is the regulation of the blood glucose, breathing rate, and heart.
Are blood glucose levels regulated by positive feedback?
No, blood glucose concentration is regulated by negative feedback. When blood sugar levels are too high, the alpha particles in the pancreas' islets of Langerhans signal the pancreas to produce more insulin, which regulates the sugar level by stimulating the liver and other body cells to absorb more glucose at convert it into either glycogen or fat. This lowers the blood sugar concentration. If it were positive feedback, high blood sugar levels would encourage the production of more glucose to increase the blood sugar concentration.
Is blood calcium level a positive or negative feedback mechanism?
positive
What are hormonal proteins that regulate glucose levels in blood?
insulin
What is the negative -feedback mechanism?
The body has several negative feed back mechanisms. In negative feedback loops our body will seek to reverse th direction of a stimulus. Meaning our body dislikes the stimulus, it will attempt to reverse it. Some examples: blood pressure, temerature control, blood glucose levels.
What organs are involved in the feedback mechanism responsible for regulating blood pressure?
The kidneys, heart, blood vessels, and brain are involved in the feedback mechanism that regulates blood pressure. The kidneys help control blood volume and release hormones that affect blood pressure, while the heart adjusts its rate and strength of contraction. Blood vessels can constrict or dilate to regulate blood flow, and the brain receives signals and sends instructions to maintain blood pressure homeostasis.

What is a feedback mechanism involving the human pancreas?
The level of sugar in the blood is affected by the amount of insulin in the blood.
