What are antigens determining blood type carried on?
Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.
Which group is the universal donor and why?
O negative blood group is universal donor, it is bcz it haz no agglutinogen (antigens which r specific proteins on the surface of RBCs), so when transfused there will be no agglutinogen in it to react with agglutinins(defencive prteins /antibodies) present in the recipients blood. O (oh) is actually zero that indicates that no antigens are present on RBC surface.
What are the different kind of human cells?
I know that there are red and white blood cells that are made up of antigens and antibodies as well as plasma and platelets. RBCs and WBCs are the main cells
What r antigens in a human body?
Antigens are substances that cause an immune response in the body by identifying substances in or markers on cells
How is blood type o a universal doner?
There are 4 blood types (A, AB, B, and O) excluding the pos or neg aspect, which are all based on the Antigens on the surface of the Red Blood Cells (RBCs). These antigens are what Antiboies detect and bind to and, because antibodies each bind two antigens, they join up all the cells making massive structures that cannot flow through the blood and cause clots. So for example the A antigen will be detected by the anti-A antibody and cause the clott to be forlmed. For this reason we do not have in our systems the antibodies capable of dececting our own antigens, so if you have A antigens (type A blood) you will have only anti-B antibodies and vice versa. If you have both A and B antigens (AB blood) you will have neither anti-A nor ant-B antibodies. If you have no antigens (type O blood) you will have both the anti-A and anti-B antibodies. Recieving donor blood which as antigens to which your own antibodies will be atracted will mean that the blood you receive is clotted up. For exampl is a type A (has anti-B antibodies) receives type B blood (has B antigens) then the antibodies will bind the donor cells. However if a type AB (no antibodies) receives any sort of donor blood it will accept it freely as there are no antibodies tobind any antigens. This is why AB type is known as the Universal Reciever, as it can receive blood from any blood type donor. So if a type O (with both antibodies) receives A type or B type or AB type donor blood then it has antibodies that will bind any of them causing a clot. However O type blood also has no antigens on it RBCs so no matter what antibodies are present the cells will not be bound. This means tha O type donor blood can be put into any resipient without feer the recipients antibodies will bind the cells, and thus O type blood is known as the Universal Donor.
Can type b pos get o negative ffp's?
No, the only people who should receive type O FFP are people with type O blood. If someone (e.g., the donor) has type O- blood, that means that their red blood cells (RBCs) do not express the A/B/D antigens, which means that their plasma willcontain antibodies against those antigens. A B+ recipient has RBCs which express the B and D antigens, so if that person is given FFP from an O- donor, an incompatibility reaction will result.The thing to remember is that ABO typing is based on the RBC antigens, whereas antibodies are present (or not) in the plasma. So inasmuch as O- is the "universal donor", that's with respect to "PRBCs" (packed red blood cells, the form in which blood transfusions are given; whole-blood transfusion is not performed anymore). By the same token, AB+ is the universal recipient for RBCs. But the situation for FFP is exactly reversed: type AB+ is the universal donor for FFP, and O- is the universal recipient.
What is meant by Rhesus Null?
Rhesus null (Rhnull) phenotype is caused by the deletion of Rh-associated glycoproteins (RHAG) expression on red blood cells (RBCs). Individuals with Rhnull phenotype have RBCs that do not express any of the Rhesus antigens because they cannot be targeted to the RBC membrane. The absence of the Rh complex alters the RBC shape, increases its osmotic fragility, and shortens its lifespan, resulting in a hemolytic anemia that is usually mild in nature. These patients are at risk of adverse transfusion reactions because they may produce antibodies against several of the Rh antigens.
Where are theblood type antigens found?
Antigens are found in the immune system. They provoke an adaptive immune response.An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. They can be found anywhere in your environment. Some are found on the surface of red blood cells. This one reason why you can not receive just any blood type.
What is the clumping together of RBCs by antibodies?
coagulation- is not the correct answer! The correct answer from my "Anatomy and Physiology" book is Agglutination
Does a RH negative individual normally contain anti RH antibodies?
No. Rh-antibodies only develop in cases of pregnancy, miscarriage or a blood transfusion like if you have rh-negative blood you got AB blood. Your RH-antibodies then work to attack the foreign substance, the RBCS. In the fetus, loss of RBCS means the rise of bilburin and could eventually lead to brain damage or (kernictous), and also have low muscle tone(hypotonia)
Why is it important to get the right blood type during a transfusion?
Actually blood group of a person is determined by the antigens(A special protein) present on the surface of all the red blood corpuscels(RBCs) in the body.The body's antibodies do not effect the RBCs of the same type but RBCs with any other type of antigen are attacked by the antibodies and immediately sticking of RBCs begins(called agglutination) causing a great risk to the life of the patient.Threfore, care is taken to match the blood groups of donor and recipient during blood transfusion.
Can someone have more then one type of blood type?
A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens that stem from one allele (or very closely linked genes), collectively form a blood group system.[1] Blood types are inherited and represent contributions from both parents. A total of 30 human blood group systems are now recognized by the International Society of Blood Transfusion (ISBT).[2]Many pregnant women carry a fetus with a different blood type from their own, and the mother can form antibodies against fetal RBCs. Sometimes these maternal antibodies are IgG, a small immunoglobulin, which can cross the placenta and cause hemolysis of fetal RBCs, which in turn can lead to hemolytic disease of the newborn, an illness of low fetal blood counts which ranges from mild to severe.[3]
