. Structure and Functions of Blood Vessels \n  Structure Functions \nArteries The walls (outer structure) of arteries contain smooth muscle fibre that contract and relax under the instructions of the sympathetic nervous system.\n   Transport blood away from the heart;\n \n  Transport oxygenated blood only (except in the case of the pulmonary artery).\n \n \n \nArterioles Arterioles are tiny branches of arteries that lead to capillaries. These are also under the control of the sympathetic nervous system, and constrict and dialate, to regulate blood flow.\n   Transport blood from arteries to capillaries;\n \n  Arterioles are the main regulators of blood flow and pressure.\n \n \n \nCapillaries Capillaries are tiny (extremely narrow) blood vessels, of approximately 5-20 micro-metres \n(one micro-metre = 0.000001metre) diameter.\nThere are networks of capillaries in most of the organs and tissues of the body. These capillaries are supplied with blood by arterioles and drained by venules. Capillary walls are only one cell thick (see diagram), which permits exchanges of material between the contents of the capillary and the surrounding tissue. \n   Function is to supply tissues with components of, and carried by, the blood, and also to remove waste from the surrounding cells ... as opposed to simply moving the blood around the body (in the case of other blood vessels);\n \n  Exchange of oxygen, carbon dioxide, water, salts, etc., between the blood and the surrounding body tissues.\n \n \n \nVenules Venules are minute vessels that drain blood from capillaries and into veins. Many venules unite to form a vein.\n   Drains blood from capillaries into veins, for return to the heart\n \n \n \nVeins The walls (outer structure) of veins consist of three layers of tissues that are thinner and less elastic than the corresponding layers of aerteries.\nVeins include valves that aid the return of blood to the heart by preventing blood from flowing in the reverse direction.\n   Transport blood towards the heart;\n \n  Transport deoxygenated blood only (except in the case of the pulmonary vein).

Many, many functions:\n\nThe liver produces and excretes bile required for food digestion. \n\nThe liver performs several roles in carbohydrate metabolism: \nGluconeogenesis (the formation of glucose from certain amino acids, lactate or glycerol) \nGlycogenolysis (the formation of glucose from glycogen) \nGlycogenesis (the formation of glycogen from glucose) \nThe breakdown of insulin and other hormones \n\nThe liver is responsible for the mainstay of protein metabolism. \n\nThe liver also performs several roles in lipid metabolism: \nCholesterol synthesis \nThe production of triglycerides (fats). \nThe liver produces coagulation factors I (fibrinogen), II (prothrombin), V, VII, IX, and XI, as well as protein C, protein S and antithrombin. \n\nThe liver breaks down hemoglobin, creating metabolites that are added to bile as pigment. \n\nThe liver breaks down toxic substances and most medicinal products in a process called drug metabolism. This sometimes results in toxication, when the metabolite is more toxic than its precursor. \n\nThe liver converts ammonia to urea. \n\nThe liver stores a multitude of substances, including glucose in the form of glycogen, vitamin B12, iron, and copper.

Are you asking what  the Plasma part of Blood is used for?

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.

"The liver is an astounding laboratory sustaining metabolism. Among its functions are purification of the blood, removing poisonous ammonia from proteins, detoxifying alcohol and drugs, controlling the body's sugar and cholesterol balance, making bile to digest fats, forming clotting factors for the blood and generating new blood cells. This myriad of functions makes clear why the liver is essential to life."

it has a filter(similar to a water filter) that removes waste as well as some of the red blood cells, this is way renal patients are often tired alot and need blood transfusions sometimes. it also removes water in the blood.

Spleen is useful to\n \n1) filter for your blood, cleansing it of bacteria, viruses and other debris. When blood flows through your spleen, white blood cells attack and remove any foreign invaders. This keeps your blood clean and helps protect you against infection.\n\n2) Destroying old red-blood cells\nRed blood cells have a lifespan of around 120 days, after which your spleen breaks them down. The red blood cell remains are transported elsewhere in your body where they are excreted or recycled to manufacture new red blood cells.\n\n3) Making blood cells\nBefore birth, foetuses produce red and white blood cells in their spleens. Shortly before birth the spleen loses its ability to make red blood cells and bone marrow takes over this job. The spleen continues producing infection-fighting white blood cells throughout our lives.\n\nWhat happens if spleen is removed (Living without a spleen)\nIt is possible to live without a spleen as most of its functions can be taken over by other organs. However, people without spleens are more vulnerable to all kinds of infections.

There are a number of different cell types in circulation in the blood stream. Here's a quick review:\n\nRed cells carry oxygen to the cells of the body. They are essentially bags of hemoglobin, the oxygen carrying molecule. Hemoglobin binds oxygen to iron atoms, which give the hemoglobin and thus the cells their distinctive red color. \nWhite cells (leukocytes, "clear cells") are divided into two types: \nPolymorphonuclear cells, are of three types: neutrophils, eosinophils, and basophils. \nNeutrophils fight bacterial infection. They form pus and are the chief ingredient of an abscess. See band cells. \nEosinophils are cells which are strongly related to allergy and the recognition of foreign things in the body such as parasites. \nBasophils are cells that are also part of the allergy and parasite recognition system.\nLymphocytes are the virus killers. There are two types of these: \nT-cells which remember what germs we've been exposed to and how to kill them. T-cells are the key component of the immune system that is missing in AIDS. \nB-cells that secrete the actual antibodies that attach to viruses and bacteria and identify them as things to be destroyed - rather like tagging the target with a laser so that the smart bomb will home in and blast the target. \nMonocytes are cells that are related to lymphocytes but have a killing and cleaning function. They cruise through the tissues of the body cleaning up debris and killing any bacteria they find. They are often increased in viral infections - a reassuring finding that your doctor may note on your child's blood count. See mononucleosis. \nPlatelets are the cells that plug leaks in the vascular system, the clotting cells. \n\n What are the different blood groups?   \n   The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.\n\nThere are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.\n\nNobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.\n\n \n\n \n   \n    AB0 blood grouping system   \n    According to the AB0 blood typing system there are four different kinds of blood types: A, B, AB or 0 (null).\n\n \n   \n   Blood group A\nIf you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.\n\n\n\n \n   \n   Blood group B\nIf you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma.\n\n\n\n \n   \n   Blood group AB\nIf you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma.\n\n\n\n \n   \n   Blood group 0\nIf you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.\n\n \n\n \n   \n    Rh factor blood grouping system   \n \n \n   Many people also have a so called Rh factor on the red blood cell's surface. This is also an antigen and those who have it are called Rh+. Those who haven't are called Rh-. A person with Rh- blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance). But a person with Rh- blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh+ bloo
