Blood Types A B AB O
2
Four major types of blood .
A, B, AB, and O. Inherited from parents. Determined by presence or absence of an ANTIGEN on the surface of the red blood cell
3
Check your knowledge of medical history...
In 1901, Austrian immunologist: Karl Landsteiner discovered blood may be grouped into four main types. Based on the reaction that resulted when blood from different individuals were mixed. 2.01 Remember the structures of the circulatory system
4
Antigens Universal Donor O Universal Recipient AB Blood protein
Located on the surface of the red blood cell. Either the person has it or doesn’t have on the blood cell. Someone with type A blood have the A antigen, Someone with type B blood have the B antigen, type AB has both A and B antigen, and type O has neither of the antigens Universal Recipient AB
5
Antibody – a protein in the plasma that will inactivate a foreign substance that enters the body
Punnet t square Someone with type A blood has b antibodies Someone with type B blood has a antibodies Someone with type AB blood has no antibodies Someone with type O blood has a and b antibodies.
6
Rh factor In 1940, the Rh factor was discovered as a result of studying Rhesus monkeys. When blood from monkeys was injected into rabbits and guinea pigs, it clotted. 2.01 Remember the structures of the circulatory system
7
Rh factor Rhesus (Rh) factor is an inherited trait that refers to a specific protein found on the surface of red blood cells (antigen). Blood used in transfusions must match donors for Rh status as well as for ABO blood type. Although Rh factor doesn't affect the patient’s health, it can affect pregnancy. 2.01 Remember the structures of the circulatory system
8
Red Cells Also may Contain Rh factor
If you have it, you’re Rh + If you don’t, you’re Rh – When an Rh- mother is pregnant with an Rh+ baby, the baby’s blood (usually during delivery) can mix with the mom’s blood, causing the mom’s blood to make anti Rh antibodies.
9
Rh factor If the blood has the protein, the patient is Rh positive.
If the blood lacks the protein, the patient is Rh negative. Did you know??? 2.01 Remember the structures of the circulatory system
10
If the mom gets pregnant again with another Rh+ positive baby, her anti Rh antibodies will attack the baby’s blood, causing Erythroblastosis Fetalis RHO Gam will destroy any baby blood cells in the mom, and her immune system won’t produce antibodies. Cord blood has immunity producing stem cells, is easy to transplant, and does not cause rejection That is why research is being done on umbilical cord blood.

Questions for BM#3 1. What is the universal Donor? The universal recipient? Who can receive what blood? ( Remember what we did in class) 2. Your friend has a automobile accident and needs blood. You want to donate your blood type is O+ and your friend is AB- can you donate? Why or why not? 3. Describe what RH in blood typing is and what it means if you are negative or positive.
