because in blood group A antigen A is present while not in O so it will destroy the characteristic of blood group O.
because in blood group B anti-A antibodies are present.
Usually, you can. But you will be requested to wait a year or so to make extra-double-certain that you didn't pick up any disease with the transfused blood that you'll then will pass on to someone else.
They can get a person with blood type A pregnant.
because all the contents of the blood could not travel through bigger number gauges or lesser diameter hypodermic needles
The type B blood has an antigen on the red cells identifying them as B type cells. The type A blood of the recipient contains antibodies that bind to B type antigens. These antibodies will cause the red cells of the blood in the transfusion to stick together forming solid lumps in the blood, preventing it from flowing.
O blood has no major proteins that A and B blood have. For example: If someone had B blood with its specific proteins, this person cant receive A blood because it has the specific A blood proteins that will cause bad clotting to stop it. O blood (with no different proteins) wont affect any blood.
because of the antibody-Anti gene system
siguro A na lang para maganda ang blood ng A
If it is an inherited condition, the person will be called a haemophiliac.
Type A, Rh negative red cells can be, and are frequently, transfused to AB, rh negative recipients. Type A, Rh negative whole blood, however, cannot be given to an AB, Rh negative recipient as anti-B antibodies present in the unit could cause an acute, hemolytic transfusion reaction. Whole blood transfusions are rarely used in modern transfusion medicine.
the person will die
This not entirely true while an Rh- person can not receive Rh+ blood due to the fact as stated above an Rh+ person can receive Rh- blood because there is no Rh in the blood. This is why O- people are universal donors meaning they are able to give blood to anyone, but can only receive 0- blood.
