Key concepts
3 concepts
- 1
Blood types are determined by the presence of specific proteins or glycoproteins on the surface of red blood cells (erythrocytes).
- 2
Type A blood has A proteins and B antibodies, Type B blood has B proteins and A antibodies, Type AB blood has both A and B proteins and no antibodies, and Type O blood has no proteins and both A and B antibodies.
- 3
The Rh factor is another blood protein; individuals who are Rh positive have the protein and do not produce antibodies, while those who are Rh negative do produce Rh+ antibodies.
