The role of red blood cells in the blood
The blood functions in many functions, the most important of which is to supply the cells with oxygen through the lungs, as well as to rid the body of carbon dioxide by red blood cells, which are spherical cells concave shape, without a core, surrounded by a wall containing inside contains hemoglobin that gives blood Red, and mixed with a number of proteins and iron, which facilitate the process of red blood cells with oxygen, where they are already oxygen-carrying cells, and thus increase the intensity of red color, where the color becomes red with the presence of oxygen, and in cases of union with carbon dioxide The color of the blood in the arteries is reddish, in order to oxidize the blood transfused, while the color in the veins is red and tends to blue due to lack of oxygen and the presence of carbon dioxide resulting from the combustion processes in different cells of the body to be eliminated In the lungs.
Red blood cell life cycle
The life cycle of red blood cells is relatively short compared with other cells of the body, whose life span does not exceed 120 days. The first is formed during pregnancy between the fourth and the sixth month, In the late pregnancy, the bone marrow is converted into the red bone marrow within the bones. After conception, the function of manufacturing remains linked in the bones. Cells are made in the bones of the face, shoulder, skull, spine, forearms, legs, and ribs. Spleen and analyzed, and then T. Will Hemoglobin where other materials are disposed of.
Size of red blood cells
The size of red blood cells plays an important role by enabling them to carry out their multiple functions of gas transport and regulation of interactions within the body. Therefore, the lack of cell size may result in the cells being unable to carry sufficient amounts of oxygen. Conversely, Which may lead to the inability of the cells to pass through the cells of the narrow blood vessels, and therefore lack of access to the necessary oxygen, as these cases result in the increase and decrease in the volume leading to multiple diseases with overlapping symptoms sometimes, and we refer in that case the need for an analysis Shows the size of red blood cells which is called MCV analysis .
Analysis of MCV results
(80.5 to 99.7) volceter, and the rate of red blood cells increases if there is a defect in the posterior tissue, which coincides with a deficiency in vitamin B12, , And folic acid. The shortfall in red blood cell count is due to deficiencies in iron and pyridoxine, which coincides with a number of diseases such as thalassemia, thyroid dysfunction and other chronic diseases.
