Definition
| What blood type is the universal recepient? |
|
|
Term
| The blood from an Rh+ baby gets into the blood of an Rh- mom during delivery and then the mom makes antibodies to attack that foreign blood. During the mom's second pregnancy, her anti-Rh antibodies cross the placenta and attack the blood of the 2nd baby with Rh+ blood. The fetus may be miscarried or born as a stillbirth. |

| Which blood type is the most common? |
|
|
Term
|
Definition
| Which blood type is the most rare? |
|
|
Term
| Because the O blood will have anti-A and Anti-B antibodies in it, which can cause a agglutination reaction in the recepient. |

| What's the name of the thread like protein that traps blood cells? |
|
|
Term
