Hemoglobin is a complex protein,which contains tetravalent iron. It is the atoms of iron that give the blood a red color. It is known that hemoglobin performs a special function - it transfers oxygen molecules to all the cells of our body. Therefore, it is very important to monitor the amount of this important protein in the blood, as the lack of oxygen causes serious disruptions in the functioning of the human body.
Normal indicators of hemoglobin inblood in children at each stage of their growing, are different figures. The highest level of hemoglobin is observed in newborns - 145-225 g / l. By the year of life, this indicator significantly changes, and as the child grows, the number of red blood cells approaches the norms of an adult. The lack of hemoglobin in children entails serious consequences, up to the delay of the child's mental development.
The norm of hemoglobin in the blood of women
A sufficient indicator of the content of bloodof red bodies in women is the figure 110-150 g / l. Often the amount of hemoglobin is affected by the menstrual cycle, this is due to the loss of a certain amount of blood. Also, the age of a woman plays here. In pregnancy, the amount of hemoglobin decreases, and this is considered normal. This fact is directly related to physiological changes in the female body. When pregnancy increases the amount of circulating blood, it prevents the production of hemoglobin. In addition, the child consumes part of the iron, which is necessary for the formation of protein.
