Glucose is one of the most important components of blood; its quantity reflects the state of carbohydrate metabolism. Glucose is evenly distributed between the formed elements of the blood and plasma, with some predominance in the latter. The concentration of glucose in arterial blood is higher than in venous blood, which is explained by its continuous use by tissue and organ cells. The concentration of glucose in the blood is regulated by the central nervous system, hormonal factors, and the liver.
