Regulation of Blood Glucose in the Human Body

Adjustment of Blood Sugar Value in the Human Cannon (1989) uses the term dynamic balance to describe the consistency of the internal environment, and an adjustment integration mechanism is designed to maintain it. He also pointed out how the system responds to emergency situations by attempting to meet sudden external demands on the human body (1). Homeostasis is important to the human body. Because homeostasis maintains an optimal environment for various processes to occur.

Blood glucose control is a process in which the blood (mainly glucose) levels are maintained by the body in a very short range. This precise regulation is called glucose homeostasis. Insulin, which lowers blood glucose and raises glucagon, is the most common hormone, but recently discovered other glucose regulating hormones expanded the understanding of this process. When the blood glucose level drops to a dangerous level (such as extremely vigorous exercise or long food shortages), the pancreatic alpha cells release glucagon and this hormonal action on the hepatocyte increases the blood sugar level. They convert glycogen to glucose (a process called glycogenolysis). Glucose is released into the bloodstream, raising blood sugar

Glucose is the main sugar in the blood. The terms "blood glucose" and "blood sugar" are used interchangeably. Glucose is used in almost all cells in the body and can circulate freely in the body. It is the preferred energy source in the brain. Muscle cells will greed out glucose from blood and import it, will boost energy rapidly. Some cells such as erythrocytes can only use glucose as energy. Glucose can be stored in various forms in the body like liver glycogen. When glucose storage is low, the liver can produce new glucose through the gluconeogenesis process.

Under normal metabolic conditions, the body relies on free glycemia as the main energy source. Blood glucose levels are strictly controlled; due to consumption of blood glucose, the pancreas releases glucagon, which stimulates the liver to convert stored glycogen to glucose. Glycogen storage is usually supplemented after meals, but supplements are supplemented before supplementation, the body starts to starve to hypoglycemia. After the glycogen storage is exhausted, the fatty acid becomes the main metabolic fuel for the next 2 to 3 days. First, when non-brain tissue uses fatty acids as its metabolic fuel, the use of glucose in the same tissue is stopped, so the brain continues to use glucose. Therefore, when fatty acids are broken down into energy, all remaining glucose becomes available in the brain. Essentially, the body consumes fat cell stored first, and then moves to the muscle.
