In this case, the pathogenesis of this type of anemia is the constant long-term blood loss, which can not be completely compensated because of the low rate of regeneration of the erythrocyte germ of the hematopoiesis. Often, the reason for the low hemoglobin content in a unit of blood volume during the period of gestation is the chronic foci of blood loss, which is the basis for the development of posthemoragic anemia. Such anemia in pregnancy is not widespread. In the case of its inherent etiology, a decrease in the hemoglobin content manifests itself immediately after birth and this has a hereditary character. Hemolytic anemia can be congenital in nature or be acquired. It is necessary to classify these changes and identify three main types of anemia - hemolytic, posthemorrhagic and scarce anemia. Talking about the reduction of hemoglobin in a unit of blood volume, it is a question of so-called anemia, which can have many causes. But for the normative index of the hemoglobin content, it is very important to have a normal level of iron as a component of the heme. Therefore, hemoglobin deficiency, especially in pregnant women, can cause serious disruption in the health of both mother and child. Such a complex structure of hemoglobin and provides its main function in the transfer of oxygen and maintenance of cellular respiration. It is the trace element of trivalent iron that attaches an oxygen molecule, and then gives it to the cell during oxidation. The hemoglobin molecule itself contains a globin protein on which the heme is configured - it is a complex prostacyclic compound that contains in the center an iron molecule. Erythrocytes provide the transfer of the oxygen molecule from the lungs to all cells of the female body precisely due to the content of hemoglobin in its composition. Hemoglobin is the main component of erythrocytes - red blood cells.
