what methods did charles drew use to store whole blood?
930252
refrigerated storage see http://en.wikipedia.org/wiki/Charles_Drew#Advanced_study\n\nGood Luck!!!

Depends on what grade you're in. You need something red, and some way of showing the path the blood is taking. Perhaps you should make a big cardboard or foam human body, and tape red strings all across the body in a realistic model of the human circulatory system.

a chemical analysis of blood shows that it contains an abundance of uric acid, a chemical substance which can be injurious to human health.\nin the human being it is excreted as a waste product and in fact we are told that 98% of the body's uric acid is extracted from the blood by the kidneys and removed through urination.\nnow, the wielder of the knife, makes an incision through the jugular veins, leaving all other veins and organs intact. And this causes the death of the animal by a total loss of blood from the body, rather than an injury to any vital organ.\nand as you know that pigs have no neck so, you cannot slaughter it and then most of the blood would congeal in its veins and would eventually permeate the flesh. \nThis implies that the animal flesh would be permeated and contaminated with uric acid and therefore very poisonous; only today did our dieticians realize such a thing.

MOST blood is transfused as pRBC's (packed red blood cells). Red blood cells have no nucleus, and therefore carry no DNA. \n\nRarely whole blood is transfused which contains DNA carrying white blood cells, usually have too many cell surface proteins that are recognized as not self (or foreign) and are destroyed.

i don't know them all...but i'll try out some! =D\n1.tissue\n2. red blood cells [not sure though, sorry]\n3. blood plasma\n7.white blood cells\n8.platelets\n9.1%\n10.haemoglobin\n\ni recalled these from what i studied before....hope they're not too far off!! =D i tried!! =D

Embalming is essential been the same since around the American Civil War. An artery is opened in the deceased's body, and embalming fluid is pumped into it. The pressure causes blood to drain concurrently from an open vein.\nIn addition, the hollow organs and viscera have their contents removed with t tube-like instrument and some sort of suction device. A strong embalming fluid is then put into the cavities to retard decomposition.\nMost improvements have involved improved embalming chemicals. Embalmers no longer have to mix their own fluids, dyes are often included in the arterial fluids, and the most dangerous chemicals are no longer used. In additions, several items have been invented that allow exposed tissues to be dried out, which allows for fillers or waxes to be used to recreate a natural appearance on someone who may have experienced trauma. \nSeveral items have been developed in the last few decades that help create a natural shape to a person's eyes and mouth. For instance, plastic caps have been developed that help keep eyelids closed as the tissues dry out a little bit. Also, many innovations for embalming machines have developed that allow for precise pressure and rate of flow during injection. This is helpful to reduce swelling.\nFinally, techniques have been developed that allow a deceased person to be a full bone and tissue donor, and still look nice for his/her viewing. For instance, PVC pipes can be used to hold the shape of limbs instead of long bones.

Are you asking what  the Plasma part of Blood is used for?
434938
Bound and unbound. Bound with hemoglobin as a carrier (red blood cells) and simply dissolved in plasma (in the same way you can dissolve air in water by shaking a half full bottle up).

*One drop of blood contains a half a drop of plasma, 5 MILLION Red Blood Cells, 10 Thousand White Blood Cells and 250 Thousand Platelets. \n*You have thousands of miles of blood vessels in your body. "Bill Nye the Science Guy" claims that you could wrap your blood vessels around the equator TWICE! \n*Keep your heart healthy...it's going to have to beat about 3 BILLION times during your lifetime! \n*Parts of the Circulatory System\nThe circulatory System is divided into three major parts:\n\nThe Heart \nThe Blood \nThe Blood Vessels\n*Your blood carries nutrients, water, oxygen and waste products to and from your body cells.

The 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\nvisit this website for more information \nhttp://en.wikipedia.org/wiki/Red_blood_cell

They prevent the blood from going backwards into the previous chamber.

Some "getting around the subject" language from the Red Cross site:\n\nThere is never a fee for the blood itself. The Red Cross charges for expenses incurred in recruiting and educating donors, keeping accurate donor records, collecting blood by trained staff, processing and testing blood in a state of the art laboratory, and storing and distributing blood.

Blood actually comprises 7% of total body weight.  In an average size, 150-pound man, the volume of blood is about five quarts. \n\nListed below is a website with more info about blood, in the form of quizzes.

your blood is being replaced all the time, your red cells have a shelf life of 120 days then it is broken down and then replaced in the body. in a blood bag there is no rejeneration process and therefore the cells just die, becuase a donation is taken from the circulation where all the cells are even distributed then a portion of the red cells are 120 days old, and away to die, etc. the shelf life is a time when the proportion of fresh cells outbalances the dead cells, includes a change in pH.

a glass vial?    like a test-tube?    or a vacutainer tube (those things they use to draw blood into)?\n\nhow many do you need?\n\nhow soon do you need them?\n\nI could maybe 'hook you up'....

Right after the donation the blood components are separated into Platelets ( good for 5 days), Plasma ( frozen good for 1year) and red blood cells ( good for 30 days). The testing is done on the extra tubes taking during donation. Testing is done for some chemistry, infectious disease ( HIV, west Nile, Hepatitis B, C, and many more). The blood is typed (A,B,AB,O and RH+/-). It is also tested for poss. bacteria contamination. A complete blood count is performed. After all the test pass acceptability, the components are released to be given. All components are constantly monitored regarding the storage temp.\nBefore blood components are given the recipient is tested to be compatible to the product. ( same blood type and compatible cross match with the donor).\nThe is a lot of checking and double checking involved in blood banking. If you need more or specific info just e-mail me.\nbeen working in blood bank for 20+ years.

Chemical reagents are not used to dilute blood. Depending on the test needed, some have a non clotting agent put in. Others let it clot and take off the serum to test for various reasons. What you are probably referring to is an agent to either stop clotting or preserve the specimen.
