B |
A mismatch of blood types during a transfusion is dangerous because ________. A clotting factors in the donor’s blood will cause unwanted clots known as thrombus B preformed antibodies in the recipient’s blood will bind and clump (agglutinate) the donated cells C white blood cells from the donor’s blood cause inflammation D antibodies in the donor’s plasma will attack and kill the recipient’s healthy blood cells |
|
C |

If you centrifuge (spin) whole blood, you will find the red blood cells (erythrocytes) at the bottom of the tube and white blood cells atop them. This implies that ________. A red blood cells are larger than white blood cells B white blood cells are fewer in number than red blood cells C white blood cells are smaller than red blood cells D red blood cells have a greater density than white blood cells |
|
D |
