Hemacias Acima De 18000 – Red blood cells (also called erythrocytes or red blood cells) are the blood cells responsible for red blood cells and play an important role in cellular oxygenation of body tissues.

Red blood cells are the most abundant cells in the blood, composed of globulin and hemoglobin, which are responsible for red blood cells.

Red blood cells are produced in the bone marrow, stimulated by a glycoprotein hormone called erythropoietin. In addition, they have a biconcave disc shape and do not have a nucleus (anuclear) or DNA when growing.

The lifespan of red blood cells is about 120 days. After this time, they undergo hemolysis, where they are destroyed in the spleen and liver, and their products are used to create new cells.

Red blood cells are about seven micrometers in diameter and can be larger in blood containing carbon dioxide (venous blood) than in blood containing oxygen (hemorrhage).

However, these cells can undergo macrocytosis or microcytosis, increasing or decreasing the size of red blood cells, respectively.

The main function of red blood cells is to transport oxygen (O2) to all cells in the body. But they also transport carbon dioxide (CO2) and hydrogen ions.

In addition, red blood cells also make blood red. This work, in turn, is carried out by hemoglobin, in which part of the iron binds with oxygen and provides transport.

Blood contains red blood cells, which differ from person to person, depending on their behavior and emotional state. Normally, the blood of a healthy adult contains about 5 million red blood cells per cubic millimeter. In women, this figure is about 4.5 million.

This red blood cell count is done from a blood count, a blood sample collected for analysis. When viewed from the front, it shows the central field (halo) rather than the peripheral field. This is due to the distribution of hemoglobin in it.

Red blood cell synonym of target. Red blood cells have a two-layer cavity, and when projected in a plane, hemoglobin is visible in a small peripheral line, and usually “targets” it.

They are erythrocytes with reduced biconcavity. When viewed under a microscope, they lose the central clear area, are denser and smaller in diameter than other erythrocytes. Therefore, they are also called microspherocytes.

It may be caused by a genetic defect in the membrane or may occur in patients with autoimmune hemolytic anemia.

They are erythrocytes with an oval and ellipsoid shape. The reason for this change is a genetic defect in the cell’s cytoskeletal proteins.

In hereditary elliptocytosis, almost all red blood cells have this shape. However, a small number of elliptocytes/ovalocytes may be seen in thalassemia, iron deficiency anemia and megaloblastic anemia.

This may be a sign of blood deficiency. It can appear in liver diseases, in the blood of newborns, and rarely in stomatocytosis caused by hemolytic anemia.

Synonymous with red blood cells like pain. Erythrocytes get this shape due to hemoglobin C, which polymerizes and settles in the cell membrane, causing deformation.

It occurs in sickle cell disease. Sickle cell disease is an umbrella term that includes a group of hemolytic anemias, including sickle cell anemia (for more information on sickle cell anemia).

They are droplet or torn erythrocytes. Deformation occurs when the brain is stretched beyond the elastic limit, passing through the fenestration of the cord and medullary sinuses of the spleen.

This is very common in myelofibrosis, due to extramedullary hematopoiesis (yeast produces blood cells due to hypocellularity of the bone marrow). It can also be observed in patients with thalassemia, hemolytic anemia and splenectomy.

They are caused by mechanical injuries, false heart valves, thermal aggression in burns and chemical aggression by using oxidizing chemicals. If the breakdown is significant, the patient shows symptoms of hemolytic anemia.

They also present clinically as disseminated intravascular coagulation (DIC), thrombotic thrombocytopenic purpura (TTP), and hemolytic uremic syndrome (HUS).

When diabetes develops slowly, symptoms are often vague and may include tiredness, fatigue, shortness of breath, or decreased exercise. When it happens quickly, the symptoms become more severe, confusion, fainting, loss of consciousness or increased thirst. Pallor is evident only when the infection is significant. Additional symptoms depend on the severity of the anemia.

There are three main types of anemia: one is blood loss, the other is the lack of red blood cells, and the second is the death of red blood cells. The most common causes of blood loss include physical injuries and gastrointestinal bleeding. Causes of decreased production include iron deficiency, vitamin B12 deficiency, thalassemia, and many spinal neoplasms. Causes of increased destruction of red blood cells include various diseases such as cancer, diseases such as malaria, and certain autoimmune diseases. Anemia can also be classified based on the size of the red blood cells and the amount of hemoglobin in each cell. If the cells are small – microcytic anemia, if large – normocytic, if large – macrocytic anemia. In men, the diagnosis is based on a low hemoglobin of 130 – 140 g / L (13 to 14 g / dL), and in women it should be less than 120 – 130 g / L (12 to 13 g / L). dl). dl).

It is not recommended to use foods that have not been identified as the main cause of red blood. The use of the serum depends on the appearance of signs and symptoms.

They are not recommended for asymptomatic people unless the hemoglobin level is less than 60 to 80 g/L (6 to 8 g/dL).

Anemia is the most common blood disorder, affecting one-third of the world’s population.

A useful classification is based on the erythrocyte index, which divides the blood into microcytic, normocytic and macrocytic. In addition to showing the nature of the defect, such a method can also show abnormalities before bleeding.

In both physiological states, the mean corpuscular volume (MCV) may be outside the reference range for adults. In infants, the MCV is high for several weeks, but in infants it is low and gradually increases to the normal adult value during childhood. In a normal pregnancy, even if there are no other causes of macrocytosis, such as folic acid deficiency, there is a small increase in MCV. for example

Alteração Morfológica Das Hemácias

Although red cells indicate the type of diabetes, more information can be obtained from a preliminary blood test.

For example, distinguish between “pure” anemia, which indicates more bone loss, and “pancytopenia” (decreased red blood cells, granulocytes, and platelets). for example caused by bone hypoplasia, bone infiltration, or cellular damage (eg, hypersplenism). From hemolysis or bleeding, the number of neutrophils and platelets in the blood is almost always present; In infections and leukemias, the white blood cell count is almost always elevated, and abnormal white blood cells and neutrophil precursors may be present.

/L. Due to the increase in erythropoietin, it increases blood sugar and indicates the weight of red blood cells. This happens only when there is time for the development of erythroid hyperplasia in the bone marrow, for example, in acute hemolysis. An erythropoietin response occurs within 6 hours of an acute illness, the reticulocyte count rises within two to three days, peaks within 6 to 10 days, and remains elevated until hemoglobin returns to normal.

An increase in the number of reticulocytes in patients with anemia indicates a decrease in bone marrow function or a lack of erythropoietin stimulation.

A blood test is necessary in all cases of anemia. Abnormal erythrocyte morphology or inclusions in erythrocytes may suggest a definitive diagnosis. For example, when microcytosis and macrocytosis occur. for example combined iron, folic acid or B deficiency

, indices may be normal, but blood deficiency shows a “dimorphic” appearance (doubling of severe hypochronic patients). When the blood test is not enough, calculate the difference and measure the number
