Red blood cells are the most common type of blood cell and are the vertebrate body's principal means of delivering oxygen from the lungs or gills to body tissues via the blood.\n\nRed blood cells are also known as RBCs or erythrocytes (from Greek erythros for "red" and kytos for "hollow", with cyte nowadays translated as "cell"). A schistocyte is a red blood cell undergoing fragmentation, or a fragmented part of a red blood cell.\n\n\nThe diameter of a typical human erythrocyte disk is 6–8 µm; they are thus much smaller than most other human cells. A typical erythrocyte contains about 270 million hemoglobin molecules, with each carrying four heme groups.\n\nAdult humans have roughly 2–3 × 1013 red blood cells at any given time (women have about 4 million to 5 million erythrocytes per cubic millimeter (microliter) of blood and men about 5 million to 6 million; people living at high altitudes with low oxygen tension will have more). Red blood cells are thus much more common than the other blood particles: There are about 4,000–11,000 white blood cells and about 150,000–400,000 platelets in a cubic millimeter of human blood. The red blood cells store collectively about 3.5 grams of iron; that's more than five times the iron stored by all the other tissues combined.\n\nThe process by which red blood cells are produced is called erythropoiesis. Erythrocytes are continuously being produced in the red bone marrow of large bones. (In the embryo, the liver is the main site of red blood cell production.) The production can be stimulated by the hormone erythropoietin (EPO), which is used for doping in sports. Erythrocytes develop in about 7 days and live a total of about 120 days. The aging cells swell up to a sphere-like shape and are engulfed by phagocytes, destroyed and their materials are released into the blood. The main sites of destruction are the liver and the spleen. The heme constituent of hemoglobin is eventually excreted as bilirubin.\n\nThe blood types of humans are due to variations in surface glycoproteins of erythrocytes.\n\nRed blood cells can be separated from blood plasma by centrifugation. During plasma donation, the red blood cells are pumped back into the body right away, and the plasma is collected. Some athletes have tried to improve their performance by doping their blood: First about 1 liter of their blood is extracted, then the red blood cells are isolated, frozen and stored, to be reinjected shortly before the competition. (Red blood cells can be conserved for 5 weeks at −78 °C.) This practice is hard to detect but may endanger the human cardiovascular system which is not equipped to deal with blood of the resulting higher viscosity\n\n\nDiseases and diagnostic tools\n \nAffected by Sickle-cell disease, red blood cells alter shape and threaten to damage internal organs.Blood diseases involving the red blood cells include:\n\nAnemias (or anaemias) are diseases characterized by low oxygen transport capacity of the blood, because of low red cell count or some abnormality of the red blood cells or the hemoglobin. \nIron deficiency anemia is the most common anemia; it occurs when the dietary intake or absorption of iron is insufficient, and hemoglobin, which contains iron, cannot be formed \nSickle-cell disease is a genetic disease that results in abnormal hemoglobin molecules. When these release their oxygen load in the tissues, they become insoluble, leading to mis-shaped red blood cells. These sickle shaped red cells are rigid and cause blood vessel blockage, pain, strokes, and other tissue damage. Specifically, Sickle-cell disease is due to a mutation of the Glu-6 residue to Val-6 on the outside of the hemoglobin protein; this change from a polar, charged amino acid to a hydrophobic amino acid causes the structural change seen in Sickle red blood cells. \nThalassemia is a genetic disease that results in the production of an abnormal ratio of hemoglobin subunits

One is that the red bone marrow will increase its erythropoeisis (AKA RBC production) Some very competative athletes have been known to go train for months at high altitude to increase their RBC count and thus O2 carrying capacity. (nutrition must be good, iron, folic acid and B12)  Then when the sport event comes, they go down to lower altitude to compete for the event and have more RBCs than the rest of the contestants,thus possibly giving them a biological edge over others.

Red blood cell: The blood cell that carries oxygen. Red cells contain hemoglobin and it is the hemoglobin which permits them to transport oxygen (and carbon dioxide). Hemoglobin, aside from being a transport molecule, is a pigment. It gives the cell its red color (and name). \nThe mature red blood cell (RBC) is a non-nucleated biconcave disk. Thanks to this unusual shape and its hemoglobin content, the RBC is superbly suited to the transport of oxygen. \nA red blood cell is sometimes simply referred to as a red cell. It is also called an erythrocyte or, rarely today, a red blood corpuscle.\n\nWhite blood cell: One of the cells the body makes to help fight infections. There are several types of white blood cells (leukocytes). The two most common types are the lymphocytes and neutrophils (also called polymorphonuclear leukocytes, PMNs, or "polys"). \n\nLymphocytes are made in lymphoid tissue in the spleen, lymph nodes, and thymus gland. There are different kinds of lymphocytes. Lymphocytes identify foreign substances from germs (bacteria or viruses) in the body and produce antibodies and cells that specifically target them. It takes from several days to weeks for lymphocytes to recognize and attack a new foreign substance. \n\nNeutrophils are also major players in the body's defense against bacterial infections. Neutrophils are made in the bone marrow and circulate in the bloodstream. Neutrophils move out of the blood vessels into the infected tissue to attack the bacteria. The pus in a boil (an abscess) is made up largely of neutrophils. Normally a serious bacterial infection causes the body to produce an increased number of neutrophils, resulting in a higher than normal white blood cell count (WBC). When the WBC is low, there may not be enough neutrophils to defend against bacterial infections. \n\nThe white blood cell count is done by counting the number of white blood cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed leukocytosis. \n\nA normal absolute neutrophil count (ANC) is in the range of 1,500 to 8,000 cells per microliter. If the ANC is below 500 for an extended period of time, the risk of serious bacterial infection may increase significantly. A low neutrophil count is called neutropenia.

i dont know what u mean by the second question but for blood, i just make a tiny circle and make it red so it looks like blood.

Without a nucleus there is more room for haemoglobin and therefore a greater oxygen-carrying capacity.\nThe consequence is that red blood cells have a short life span; they are constantly being broken down and the parts recycled (except the haem bit which is got rid of into the gut).\nSince the red blood cells have a short life span they must continually be replaced. You can see the importance of a good supply of iron in our diet.\nYou might like to ponder over the diet of new-born mammals - there is no iron in milk.

blood, fluid pumped by the heart that circulates throughout the body via the arteries, veins, and capillaries (see circulatory system; heart). An adult male of average size normally has about 6 quarts (5.6 liters) of blood. The blood carries oxygen and nutrients to the body tissues and removes carbon dioxide and other wastes. The colorless fluid of the blood, or plasma, carries the red and white blood cells, platelets, waste products, and various other cells and substances

When a Full Blood Count (FBC) is requested the haematology analysers count the numbers of all the different blood cells - white cells, red cells and platelets. It also measures the size and shape of the cells. In healthy control patients the red cells will all be similar in size and shape, but in patients who are recovering from an anaemia, blood loss, or have received a recent blood transfusion or in patients with abnormalities of the red blood cells (thalassemia, sickle cell) the red cells can vary in size. This is measured by the Red Cell Distribution Width (RDW). So it is a variation in size of the red cells. If a patient has been anaemic, a raised RDW would be considered a good response to treatment as new healthy sized cells are being produced.

The blood is no longer infused with oxygen from the lungs.\n\nBlood is a bright red in its oxygenated form (i.e., leaving the lungs), when hemoglobin is bound to oxygen to form oxyhemoglobin. It's a dark red in its deoxygenated form (i.e., returning to the lungs), when hemoglobin is bound to carbon dioxide to form carboxyhemoglobin.

In their first few days of life, more than half of all full-term babies and as many as four out of five premature infants who are otherwise healthy develop jaundice. Although some babies are jaundiced at birth, most develop infant jaundice during their second or third day of life. This would usually disappear in 2 weeks.  Jaundice that develops or lasts more than 2 weeks can be a sign of a liver malfunction, a severe infection, an enzyme deficiency, or an abnormality of your baby's red blood cells.  Your doctor should do further testing to determine what the exact cause is.

Blood in the human body is both red and blue. Red blood is oxygenated blood and blue blood is deoxygenated blood. \n\nHowever, all blood outside of the body is red because oxygenated blood is red and deoxygenated blood becomes oxygenated through diffusion instantly upon reaching the air.

No. The mother needs to be RH- and the baby needs to be RH+ in order for the baby to have erythroblastosis fetalis, and it will happen only after the first child.
