Red blood cells are the basic cells of the blood.Data cells in the blood is much higher than the rest of blood cells.Erythrocyte disk is the correct form, which is slightly thicker at the edges. This structure helps them to be enriched with oxygen in a maximum amount during the passage of the human circulatory system.Also, red blood cells and absorb carbon dioxide.Erythrocytes

formed under the influence of erythropoietin or kidney hormone in bone marrow.It is composed of two-thirds of hemoglobin, namely protein, which in turn contains iron.A painting of red blood cells and the blood is determined by the red color of hemoglobin.These cells live on average one hundred and twenty days.Red blood cells are destroyed after their expiration in the liver and spleen.The destruction of these cells is not in any way affect the total number of red blood cells in the body, because of their constant renewal meets the bone marrow.

What functions are performed by the red blood cells

primarily red blood cells have a tissue saturated with oxygen function.Also they are created in order to transfer carbon dioxide from the lungs to the body tissues.Besides their functions include nutrient, which is an amino acid transport into tissues of the digestive system.Furthermore, erythrocytes have also a protective function that is to participate in various reactions of immunity and surface adsorption of toxins and antigens.Furthermore erythrocytes support base balance of blood.

erythrocyte level in the blood can be determined only based on a blood test.For men, this level should range from 4 to 5,1 × 10 ??per liter of blood, the number of women should be in the same frame.In newborn infants, the number of red blood cells in a liter of blood is 4.3 to 7.6 × 10 ??.

The rate of red blood cells in children

known that red blood cells are involved in a process called respiration, because they carry oxygen to tissues and organs from the lungs and vice versa withdraw from the organs and tissues of carbon dioxideand transport it back to the lungs.Also refer to the red blood cells, reticulocytes, which are by their predecessors.they are called not by cells, in turn, and red blood cells, which become red because of hemoglobin, which is included in their composition.

Children number of red blood cells varies with the age, but not by gender.values ​​according to the age of the child have been identified to indicate the rate of red blood cells in the blood.While still in the womb, in the child's blood contains from 3.9 to 5,5 x10 ??.From the first to the third day of life of a child lying erythrocytes rate of 4 to 6,6 x10 ??per liter of blood.From the fourth to the seventh day, a figure that includes the same number of red blood cells.In one month, the baby in the blood, there are from 3 to 5,4 x10 ??erythrocytes per liter.In two months, this number drops slightly, ranging from 2.7 to 4,9 x10 ??.From seven to eleven months, a normal level of red blood cell counts from 3.1 to 4,5 × 10 ??per liter of blood.In one year, the figure is 3.6 to 4,9 x10 ??.From three to twelve years, the rate of red blood cells varies from 3.5 to 4,7 x10 ??.But starting from the age of thirteen, this norm ustakanivaetsya and become as adults, namely from 3.6 to 5,6 x10 ??per liter of blood.

Reduced level of red blood cells in a child

If the analysis of your child's blood revealed a decrease in this indicator, it may indicate anemia.Anemia is a pathological condition that adversely affects the functioning of the body.With this disease mainly affects its supply.Such a disease like anemia can occur due to many reasons.This disease may be as a consequence of a primary lesion of the blood system, and symptom of various diseases.

Besides lowering of red blood cells may be due to physiological reasons, namely the presence of copious amounts of fluid in the body.But this short-term decrease in red blood cells and soon their number will come back to normal.

Elevated red blood cells in the blood of the child

If the red blood cells of the child increases, such a phenomenon is called erythremia or erythrocytosis.However, this is quite rare.Erythremia may be physiological or pathological.The phenomenon of physiological polycythemia can occur in a person who has long lived in the mountains, or in children who have long engaged in sports and physical activities.

But pathological erythremia may occur at various blood diseases, congenital heart disease, with dehydration, which occurs later diarrhea and vomiting, with a decrease in the functioning of the adrenal cortex as well as in diseases of the lungs, which in turn supply the blood with oxygen.

Sometimes in order to correctly diagnose blood disease, it is necessary to take into account the size, shape and the saturation of hemoglobin in red blood cells.

If a change in the shape of the erythrocyte, it primarily indicates some congenital diseases.These diseases can be manifested spherocytosis, elliptocytosis, cells in the form of a crescent instead of the red blood cell fragments, mishenepodobnymi erythrocytes.Also, the modified form may indicate liver damage due to poisoning by heavy metals or lead.

If the red blood cells change size, the phenomenon is called anisocytosis.In this case, you can select microcytosis, macrocytosis and a hybrid option.These events can occur if someone has been poisoned by any toxic substances.

The blood also are young, immature red blood cells called reticulocytes.They may be in the peripheral blood.The blood test is often reticulocyte count should be between 0.2 to 1.2 percent.The data rate is considered normal bone marrow activity, which in turn produce new red blood cells.If the patient has long been treated for anemia, the increase of reticulocytes is considered a good sign.But the reduced level of reticulocytes in long-term treatment of the disease is an unfavorable sign.
