Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.


Welcome to the global web. Today, in this article, I will tell you and discuss the information about Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.


Erythrocytes, also known as red blood cells or red blood cells (Greek for "red" and "wallets"), are the most abundant cells in the blood. Hemoglobin is one of its main components, and its function is to transport oxygen to various body tissues. Human erythrocytes, like the rest of mammals, lack the nuclei and mitochondria, so they gain their metabolic energy through lactic fermentation. The total cubic millimeter (or microliter) of blood that is commonly considered in the human species fluctuates between 4,500,000 (in females) and 5,400,000 (in males), 3 times more than leukocytes. Most red blood cells are called polycythemia and their deficiency is called anemia.  Erythrocytes are commonly used in clinical practice for transplantation and are referred to as transporters of drugs and nanoparticles. Dichotomous disc between 80 and 100 females in erythrocyte 7 and 100 μm thick and 5 to 7.5 μm in diameter. The cell has lost its residual RNA and its mitochondria, as well as some important enzymes; Therefore, it is unable to synthesize new proteins or lipids. Its cytoplasm is mostly hemoglobin pigmented, giving it a characteristic red color (which is darker than oxygen) and responsible for oxygen transport.
Now, this explanation applies to mammalian erythrocytes, because in other vertebrates, with few exceptions, erythrocytes lack cytokine size and are generally larger than previously described. This is because the nucleus of the remaining vertebrate red blood cells is still present.
Red blood cells are derived from compromised stem cells. Erythropoietin, which is produced in the renal tissue, induces erythropoiesis (ie erythrocytes formation) and is responsible for maintaining red blood cell mass in a stable state. Erythrocytes such as leukocytes originate from the bone marrow.
The ration of erythrocyte varies according to sex, age and geographical location. High concentrations of erythrocytes are found in high altitude, males, and newborns. Decreasing the reference range leads to a condition called anemia. This change causes tissue hypoxia. The increase in red blood cell concentration (polycythemia) is minimal.

Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.

Hemolysis occurs in the destruction of aging red blood cells and in macrophages of the spleen and liver. The essential elements, glob, and iron are preserved and reused. The heme fraction of the molecule catalyzes bilirubin and biliverdin and is eventually excreted by the intestinal tract. The breakdown of erythrocyte releases hemoglobin directly into the blood, where the molecule breaks into α and ers dimer, which binds to the transport protein, haptoglobin. This transmits dimers to the liver, where they are metabolized and excreted to bilirubin.

The morphological developmental stages of the erythroid cell (in order of increasing maturity) include the following steps:
Pluripotential stem cells.
Multiple cellular stem cells
Ancestral cell or CFU-S (spleen colony-forming unit).
BFU-E (erythrocyte diffusion-forming unit).
CFU-E (erythrocyte colony-forming unit), .last: large cell of abundant cytoplasm, large nucleus with thick chromatin, nucleoli not well defined (20–25 μm).
Basophilic Erythroblast: Basophilic cytoplasm, thick and nodular chromatin, smaller than the previous (16–18 μm), where hemoglobin is formed.
Polychromatophilic Erythroblast: It measures 10–12 μm, and the hemoglobin begins to acquire cytoplasm pink, displaying the final mitotic phase for the formation of red blood cells, nucleoli, and nuclei/cytoplasm. Added. The ratio is 4: 1.
Orthochromatic Erythroblast: It measures 8-10 μm, contains compact chromatin, and the nuclei disappear.
Reticulocyte: almost divided into mature erythrocytes. The presence of reticulocytes in the peripheral blood) implies the proper functioning of the bone marrow.
Erythrocyte, after all, is already present in the absence of nuclei and mitochondria. It has transport capacity (gas, hormones, medicine, etc.).
