|
|
Blood typing is a blood classification based on the presence of specific glyco proteins on the outer surface of RBC plasma membrane. the proteins are called...
|
antigens or agglutinonens and are genectically determined
|
|
|
Antigens(agglutoninens on outer surface of plasma membranes are usually accompanied by....
|
Antibodies (agglutinin)
|
|

increase red blood cells
b/c air is thinner, less O2, body compensates so it gets the same amount of O2 needed. |

body has no preformed so need to build anti bodies
