Blood type is a classification of blood based on the presence of certain antigens on the red blood cell. The blood types are A, B, AB and O. The Rh or Rhesus factor is another blood type system. ...
Your blood "type" denotes the kinds of antigens you have on the surface of your cells. People with type A blood have A antigens; those with type B have B antigens. If you have both kinds of antigens, you're type AB; if you have neither one, you're type O. Your immune system ...
Group AB has A and B antigens but neither A nor B antibodies. Group O doesn’t have A or B antigens but has both A and B antibodies. The third kind of antigen is called the Rh factor. You either have this antigen (meaning your blood type is “Rh+” or “positive”), or you ...
ABO blood group system, classification of human blood as determined by the presence or absence of A and B antigens on red blood cells.
Group AB has A and B antigens but neither A nor B antibodies. Group O doesn’t have A or B antigens but has both A and B antibodies. The third kind of antigen is called the Rh factor. You either have this antigen (meaning your blood type is “Rh+” or “positive”), or you ...
Who can people with AB positive blood donate to? How can type O blood, which has anti-A antibodies and anti-B antibodies, not attack Type A, Type B, or Type AB blood, when they all have the antigens for said antibodies in Type O blood? Wouldn't the antibodies attack the respective...
These are defined by which antigens are present on the surface of red blood cells: Type A blood has the A antigen on red blood cells, B has the B antigen, AB has both and O has neither. In general, the rarest blood type is AB negative and the most common is O positive. Here's...
Type O is the kind of blood thathospitals most often need. What the researchers are testing is aneasier way to make type O blood out of other kinds of blood.及全文内容可知,文章主要介绍科学家发现了一种制造0型血的新方法。故选C项。
These antigens are found with type A, B and AB blood but not with type O. More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes(酶). But large amounts of...
