The digestive system, including the pancreas and liver breaks down food.
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.
The pancreas is the organ in the body that detects changes in blood glucose levels. It releases insulin to lower blood sugar levels and glucagon to raise blood sugar levels in response to these changes.
glucagon.
The main hormone that signals the release of glucose into the blood is Glucagon, however, it is used in conjunction with other hormones which also cause a release of glucose into the blood. These are somatostatin, Adrenaline (epinephrine for Americans), Cortisol and ACTH.
The sensor in a negative feedback loop monitors the state of the variable, in this case blood glucose. For blood glucose, the sensor as well as the integrator is the Islets of Langerhans, since it contains the alpha and beta cells. Alpha cells produce glucagon, a hormone that acts on the liver to release more glucose into the blood. Beta cells produce insulin, which controls the uptake of glucose into the cells. The effectors respond to the sensor's messages, and act to maintain a variable. The effectors for blood glucose are the cells which take in glucose, as well as the liver.
The hormone that signals the release of glucose from storage is glucagon. Glucagon is produced by the alpha cells of the pancreas and works to increase blood glucose levels when they are low, such as during fasting or between meals.
Your body seeks to convert glucose to glycogen and glycogen to glucose based on hormonal signals that are secreted in response to an event. i.e. if you ate tons of sugary food, your body will secrete a hormone called insulin from the beta cells of the pancreas, so that glucose in the blood will be able to be stored as glycogen in the muscle cells.
Glucagon is a hormone that signals the liver to release stored glucose into the bloodstream, raising blood sugar levels.
Pancreas detects blood glucose level by its cells called "Islets of Langerhans." When the blood glucose level is too high, it releases insulin. When it becomes too low, the pancreas then releases glucagon to elevate a low blood glucose.
Glucose is a kind of sugar that your body needs and categorizes as "food". Glucose is what makes up your blood sugar level. If your blood sugar is too low, your pancreas detects this and releases the hormone insulin. This hormone travels aroudnt the body to get to the liver. The liver detects the insulin and takes glucose out of your blood and stores it as glycogen. Glycogen is essentially glucose in strings which the Liver stores for later use when the body is in need of glucose. This happens when the body detects the presence of Glycogon. Whenever your blood has too low sugar levels the pancreas releases a hormone called glycogon which then travels to the target organ, the Liver. The Liver, then detects the presence of the hormone glycogon, and uses up its reserves (glucose). The glucose is now sent out into your bloodstream which stabilises your sugar levels.

No, the circulatory system carries blood, nutrients, oxygen, and waste products throughout the body. Signals are carried through the nervous system, which uses electrical and chemical signals to transmit information.
