the concentration of glucose in the bloodConcentration of glucose in the blood is integrally displays the status of the internal environment. It serves not only as a source of energy needed for protein and fat, but also for the synthesis of these elements in the substrate. Yes and nervous system in combination with smooth and striated muscles can function only if the concentration of sugar ensures their energy needs. It is established that the optimal rate will be 1 g of glucose (+/-0.2) for each liter of human blood. Higher level leads to increased kidney function, increase the synthesis of glycogen and release of sugar. Decreasing the percentage of runs increase glycogenolysis under the influence of glucagon and adrenaline.

percentage of concentrations leads to an immediate reaction of the hypothalamus, and leads to correct production of adrenaline, glucagon and insulin by the adrenal glands and the pancreas. If the body percentage of glucose is reduced by half, and not even the concentration reaches 0.5 g / liter, then the brain cells will get enough energy and this will lead to increased heart rate, muscle tremor, increased sweating, dizziness, insatiable hunger, and subsequently to hypoglycemic coma. The reason for this situation is drop the amount of sugar due to starvation or an overdose of insulin. Therefore, once it is established that in the blood decreases the percentage of sugar should be intravenous glucagon, or take sucrose.mean blood glucose unlike reduction, short-term growth of sugar doesn't bear serious consequences for the organism.

If you consider that 1 litre is about 1G of glucose, and in the human body about 5 liters of blood, the concentration of sugar is equal to approximately 5g, and this despite the fact that an adult at rest consumes every minute of the blood supply 0.3 g of glucose. That is, after exhausting all her concentration in the blood, it is possible to provide the body with energy no more than 5 minutes. Therefore, whenever the consumption of carbohydrates, excess sugar accumulates in the form of glycogen, which when needed is becoming glucose. This process of self-regulation of the percentage content of substances allows to maintain a relatively constant concentration, allowing fabric the necessary energy. And when the percentage content exceeds the norm by more than 80%, all the excess leaves the body with urine while urination.
