Blood Types

Blood Types

• Blood is categorized by the presence or absence of antigens on the red blood cells
• These antigens allow white blood cells to identify your own red blood cells as your own (aka as not foreign invaders)
• The 8 major blood types are as follows: A+, A-, B+, B-, AB+, AB-, O+, and O-
• The letter (A, B, AB, O) refers to the presence or absence of A and B antigens
• The + or - sign refers to the presence of D antigen from the Rh blood group system

Type A: has A antigens

Type B: has B antigens

Type AB: has A and B antigens

Type O: has neither A or B antigens

Type X+: has D antigens (RH factor positive)

Type X-: doesn’t have D antigens (RH factor negative)

Type A+: has A and D antigens

Type B+: has B and D antigens

Type AB-: has A and B antigens

Type O-: has neither A, B, or D antigens

Blood Types

• Antibodies are used to identify and neutralize foreign objects in the body.
• You will form antibodies against any antigen that isn’t on your own red blood cells. You cannot receive blood from someone with antigens that you have antibodies against because your immune system will treat the donated red blood cells as foreign invaders.

Blood Types

• Example 1: if your blood type is A+, you have A antigens and D antigens. You do not have B antigens, so your body forms antibodies against B antigens. Therefore, you cannot receive AB or B blood because they have B antigens.
• Example 2: if your blood type is O-, you have none of the major antigens, so your body forms antibodies against all of them. You can only receive O- blood because all other blood types have antigens that you have antibodies against.
• Example 3: if your blood type is AB+, you have all of the major antigens, so your body hasn’t formed antibodies against any of them. So you can receive all blood types.

Game Time!

Rules

1. Everyone is given 4 cards. You can look at your cards, but do not show anyone else. Each card corresponds to a blood type.
2. On your turn, pick one of your cards and ask another player if they have a blood type that can be donated to that card.
1. Eg. Player A asks “Player B, do you have a blood type that can be donated to A+?”
3. If the answer is no, you must draw a card from the center
4. If the answer is yes, the player you asked must give you a card with a blood type that can be donated to the card you asked about. Set the two cards aside. This is a pair.
• Eg. Player B gives Player A a card that says O- on it, and Player A sets the A+ card and O- card aside.
5. Either response is the end of your turn. Everyone goes in a circle taking turns until someone runs out of the cards. Then, everyone counts up their pairs, and the person with the most pairs wins.
