From the process of red blood cell production, destruction and regulation, the list is summarized to

The types of anemia are as follows:

1. Secondary anemia, which is mainly caused by anemia caused by infection or chronic systemic diseases other than hematopoietic tissues.

2. Hemolytic anemia refers to anemia that occurs when red blood cell damage is accelerated and bone marrow hematopoietic function is insufficient.

3. Aplastic anemia, which is caused by hematopoietic dysfunction or bone marrow failure, due to some reasons, leads to varying degrees of pancytopenia, anemia, bleeding or infection.

4. Iron deficiency anemia, if the intake is insufficient or too much is lost, it will lead to iron deficiency in the body, which will affect the synthesis of red blood cell hemoglobin and lead to iron deficiency anemia.

Causes: 1. Hemolytic anemia caused by external defects of red blood cells.

External defects, usually acquired, can cause hemolysis by chemical, mechanical, or physical, biological, and immunological damage. Hemolysis can be intravascular or extravascular.

2. Abnormalities of red blood cell membranes.

The pyruvate kinase contained in the membrane, these enzymes or glucose 603 dehydrogenase, G6PD deficiency, and broad bean disease can cause anemia.

3. Aplastic anemia.

Bone marrow hematopoiesis is not good, we call it aplastic anemia, and it cannot make blood, which may be caused by bone marrow or immune factors.

4. Anemia caused by disease.

Anemia caused by leukemia or other malignant tumors.

1. Iron deficiency anemia. The core of red blood cells is a bivalent iron ion, and this anemia occurs if there is an excessive lack of iron intake;

2. Viral anemia. When the human body is infected with septicaemia, the bacteria invade and destroy the structure of red blood cells, resulting in the loss of a large number of red blood cells.

3. Obstacle anemia. Hematopoietic stem cells and the hematopoietic microenvironment are dysfunctional, and the hematopoietic red pulp is replaced by fat, resulting in pancytopenia.

First of all, anemia is caused by a lower than normal concentration of red blood cells and hemoglobin. Erythropoiesis requires iron, folic acid, and vitamin B12Iron deficiency results in decreased hemoglobin synthesis, causing hypochromic microcytic anemia, known as iron deficiency anemia.

Deficiency of the latter two can lead to megaloblastic anemia. In general, the destruction of red blood cells is a normal physiological process and does not lead to anemia.

In short, iron disappears with red blood cells, and hematopoietic cells cannot be supplemented with iron, so they are anemic! Besides, iron can't be reused, I hope it can help you.

Answer]: A causes of erythrocytopenia include: excessive destruction of red blood cells, which is more common in hemolytic anemia, including abnormal hemoglobinopathies, paroxysmal sleep Luchun hemoglobinuria, Zhudanchai confessional dysgenesis anemia, immune hemolytic anemia, and hypersplenism; Insufficient erythropoiesis, mainly due to insufficiency or impaired utilization of hematopoietic raw materials; Bone marrow hematopoietic function is accompanied by decreased tolerance, such as aplastic anemia.

Answer] :d analysis: Anemia with excessive destruction of red blood cells is also known as hemolytic anemia.

Globin dyspoietic anemia such as marine anemia or marine anemia. It is a group of hereditary hemolytic anemias caused by the destruction or complete inhibition of one or more synthesis of hemoglobin chains, which is caused by excessive destruction of red blood cells. The rest are not anemia caused by excessive destruction of red blood cells, but anemia caused by decreased production.

Master the knowledge of "hemolytic anemia".

The raw materials for the production of red blood cells are protein, iron, a variety of amino acids, vitamins B6, B2, C, E and trace elements such as copper, manganese, cobalt, zinc, etc. The main influencing factor is erythropoietin (EPO).

Early red blood cell growth relies on a regulatory action called burst boosters. Late erythroid progenitor cells are primarily regulated by erythropoietin (EPO). EPO is mainly produced by kidney tissue, which regulates the feedback loop of erythropoiesis, keeping the number of red blood cells in the blood relatively stable.

Mature red blood cells do not have a nucleus and are rich in hemoglobin. Hemoglobin is an iron-containing protein that is red in color. It is easy to bind to oxygen where the oxygen content is high, and it is easy to separate from oxygen in places with low oxygen content.

This property of hemoglobin allows red blood cells to transport oxygen.

In addition to oxygen, red blood cells can also transport some carbon dioxide from tissue cells.
