The mechanism of homeostatic regulation of the concentration of glucose in blood or glycemia is described. The physiological principle of balance is used to understand the amount of glucose in the blood. The physiological processes that increase blood glucose (glycogenolysis, gluconeogenesis, lipolysis and proteolysis) and those that decrease it (glycolysis, glycogenesis, lipogenesis and proteogenesis) are described. In addition, it describes how the body detects the concentration of glucose in the blood (glucose-sensitive chemoreceptors) and how it responds to increases and decreases in blood glucose through the endocrine system. That is, through endocrine cells that produce insulin and glucagon, and through sympathetic neurons and hypothalamic neurons that govern the adrenal and somatotrophic axes. The effect of insulin, glucagon, norepinephrine, adrenaline, cortisol, and growth hormone on blood glucose is described. I share the link of my channel. / @mauriciogiuliodori
