What is the red blood cells? Red blood cells – are cells of human blood, as well as some vertebrates and invertebrates, which contain hemoglobin and carry oxygen transport from lungs to tissues and carbon dioxide from tissues to the lungs. Human red blood cells are biconcave shape, red color and have dimensions of 8.7 microns. Credit: Brian Roberts-2011. The life span of red blood cells ranges from 120 days. Red coloration is caused by red blood cell hemoglobin, which represents the majority of erythrocyte formation of red blood cells eritrotsita.Obrazovanie is in the process of erythropoiesis in the bone marrow, where in the process of proliferation and differentiation of stem bone marrow into the bloodstream within a few hours into a eritrotsit.Funktsii eritrotsitovSamoy main function of red blood cells caused by the hemoglobin contained in them is breathing, that is, carries oxygen from the lungs to the tissues and carbon dioxide from the tissues to legkim.Pitatelnaya. Is conveyed from the amino acids of the digestive system to tkanyam.Fermentativnaya. Follow others, such as Hunter Pond, and add to your knowledge base. Red blood cells are involved in enzymatic reactions, because their surfaces are attached to many fermenty.Zaschitnaya.
Red blood cells are able to adsorb toxins and antigens, as well as participate in immune and autoimmune reaktsiyah.Regulyatornaya. Red blood cells help to maintain the acid-base ravnovesiya.Norma red blood cells of human normal blood count is when the number of red blood cells in males is 4.0 * 1012/l-5, 5 * 1012 / l, while Women – 3.5 * 5.0 * 1012 1012/l- / liter. The children in the normal number of red blood cells varies depending on age, which is given in tablitse.VozrastZhenschiny, 10 2/lMuzhchiny, -10 2/lKrov of pupoviny3 ,9-5 ,53,9-5 ,51-3 dnya4 ,0-6 ,64,0-6, 61 ned3 ,9-6 ,33,9-6, 32 "3,6-6,23,6-6,21 mes3 ,0-5 ,43,0-5 42 "2,7-4,92,7-4,93-6" 3,1-4,53,1-4,50,5-2 goda3 ,7-5 ,23,4-5 ,03-12 years of age3 ,5-5 ,03,9-5 ,013-16 "3,5-5,04,1-5,517-19" 3,5-5,03 ,9-5, 6Snizhenie number of red blood cells decrease in number of red blood cells is one of the hallmarks of anemia associated with blood loss, hemolysis, vitamin B12 deficiency outflow of interstitial fluid in the bloodstream decreases otekov.Uvelichenie number of red blood cells As described in the article, the causes of high and low hemoglobin, increased red blood cell counts may be at eritremii and eritrotsitozah.Eritremiya (polycythemia, Vakeza disease), or primary polycythemia – a condition caused by malignant transformation of cells of the dining room of the polypeptide, which starts increased division of progenitor cells erythrocytosis.
