•Describe the differences between red blood cells, white blood cells, plasma and platelets.?

red blood cells are circular cells that transport oxygen throughout the body. white blood cells are part of the immune system and fight infection and foriegn objects that enter the body. plasma is the liquid part of blood, and platelets are the part of the blood that cause clotting.

The spleen filters blood and gets rid of the old and dying red blood cells.  The spleen also hold extra blood within it.\n\nBone marrow is where red blood cells are produced.

The main blood types are A, AB, B, and O.  These blood types are fromed due to a specific type of protein found on the red blood cells.  A type blood has A protein, while B has B protein.  O does not contain any protein so the O stands for zero.  AB contains both A and B proteins.  Along with this there is the Rh positive and negative type.  This is independent of the ABO grouping so  you can have all the ABO types plus the positives and negatives as well.  So far ther are 8 distinct types.  Along with this there is a M and N type.  This is more subtle and it is usually not tested for. So now we have 16 different types possible.

Blood plasma is the liquid component of blood, in which the blood cells are suspended. Serum is the same as blood plasma except that clotting factors (such as fibrin) have been removed.\n\nPlasma resembles whey in appearance (transparent with a faint straw colour). It is mainly composed of water, blood proteins, and inorganic electrolytes. It serves as transport medium for glucose, lipids, hormones, metabolic end products, carbon dioxide and oxygen. (Oxygen transport capacity of plasma is much lower than that of the hemoglobin in the red blood cells; it may increase under hyperbaric conditions.) Plasma is the storage and transport medium of clotting factors and its protein content is necessary to maintain the oncotic pressure of the blood.\n\n*As a side note: you can also donate your plasma for money. Just look up clinics in your area.

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.

Red blood cells are also known as RBCs or erythrocytes (from Greek erythros for "red" and kytos for "hollow", with cyte nowadays translated as "cell").

Blood plasma is the liquid component of blood, in which the blood cells are suspended. Serum is the same as blood plasma except that clotting factors (such as fibrin) have been removed. Blood plasma contains fibrinogen.\n\nPlasma resembles whey in appearance (transparent with a faint straw colour). It is mainly composed of water, blood proteins, and inorganic electrolytes. It serves as transport medium for glucose, lipids, hormones, metabolic end products, carbon dioxide and oxygen. (Oxygen transport capacity of plasma is much lower than that of the hemoglobin in the red blood cells; it may increase under hyperbaric conditions.) Plasma is the storage and transport of clotting factors and its protein content is necessary to maintain the oncotic pressure of the blood.\nhttp://en.wikipedia.org/wiki/Blood_plasma

Most blood transfusions are of packed red cells and not serum/platelets or white cells.  Red cells have no nuclei/genetic material.  Blood type and rH factor are important and mismatch can yield a type of rejection.  The white cells are ultimately "rejected"   In someone with an inactive immune system (chemo patient) the blood can attack the recepient!

Blood is composed of 6 different kinds of cells (red blood cells and 5 types of white blood cells) and platelets, which are just pieces of cells.\nIn a normal person, there is an average, normal number of each kind of cell.  The numbers of the cells can increase, and (appear to) decrease if the person is sick.\nFor example, if someone has a high neutrophil count then it is suggestive of a bacterial infection or tissue damage.  This is because neutrophils ingest and destroy bacteria and dead tissue.  They're the "clean-up" cells.\nAn increase in lymphocytes indicates a viral infection because lymphocytes fight in cellular immunity.  Meaning that they kill cells that are infected/infectious.\nEosinophils are increased in allergies and parasitic infections (which stimulate allergic reactions).  Their function is to limit the damage done by basophils.  Basophils release histamine (makes your nose run and eyes water) and heparin (which makes your blood not clot).\nMonocytes are also clean up cells and right now I can't remember why they are increased - sorry.\nRed blood cells are the most abundant.  Their main function is to provide all of the tissues of the body with oxygen.  There's lots of tissues and they need lots of oxygen, so there's lots of red blood cells.\n\nI'm not taking into account diseases like lymphomas, leukemias, and polycythemia.  These are disease in which some blood cells are increased because the mechanism that controls their amounts has gone wonky and has nothing to do with the function of the cells.\n\nI hope this explaination helps - and is clear enough to understand.

Is this a question? I'm not sure, but here's a couple of websites where you can get answers about blood transfusions:\nhttp://www.bloodtransfusion.com/\n\nThese are about blood substitues:\nhttp://www.medicine.mcgill.ca/artcell/2000Editorial.htm\nhttp://www.patletendre.com/tm-reading-alternatives.html\n\nHope this helps.

One single drop of blood contains around a million erythrocytes, or Red Blood Cells \n and FYI, the average life span of a Red blood cell is 120 days!!!

All the cellular components of the blood derive from the bone marrow. Erythroid progenitors give rise to red cells, megakaryocytes split themselves into tiny pieces to give platelets, and hematopoyetic pluripotent stem cell progenitors give rise to myeloid and lymphoid progenitors The first of them give rise to granulocytes (mastocytes, eosinophyls, basophyls and neutrophyls) and monocytes (which later become macrophages). The lymphoid progenitors give rise to T and B lymphocytes.

You can think of blood made from two basic components. First are the cellular components or the red and white blood cells. They are made in the bone marrow and some white cells in the lymph nodes. The watery part is the blood plasma and contains all the hormones, the water, the sugars, dissolved blood gasses, plasma proteins made in the bone marrow and liver and a host of other substances.
