ANATOMY

Unit 3 Notes:Blood Typing

(1) Antigens and Antibodies

• Antigens:– The protein ID tags on the surface of all cells.– Used to identify the different types of cells.– Determine blood type.

• Antibodies:– The free-floating proteins in blood used to bind

to, and identify foreign cells.

• Antibody & Antigen Options:– A , B , Rh (“positive”)

(2) The Blood Types• A , B , AB, O

• A+ , B+ , AB+ , O+

• “Negative” Blood Types = Non-Positive

(3) Donating• Can donate to anyone who has AT LEAST ALL of

the same antigens you have.

• *The person you donate to could have MORE antigens than you, but they cannot have LESS.

• Example:– Blood Type AB = A and B antigens– They can donate to anyone who at least has A and B

antigens.– They can donate to…

• Type AB• Type AB+

(4) Receiving• Can receive from any person whose

antigens will not match your antibodies.

• Example:– Blood Type AB = A and B antigens– They would have only the Rh-antibodies.– They only CAN’T receive positive blood types…– So they CAN receive ANY negative types:• A , B , O , AB

(5) Type O• Antigens = None

• Antibodies = A, B, and Rh

• Can Donate To:– All blood types – They have zero antigens so no one’s body will detect it

as foreign!

• Can Receive From:– Only Type O– They have every type of antibody

(6) Type O Positive• Antigens = Only Rh

• Antibodies = A and B

• Can Donate To:– All positive blood types – They only have the Rh antigen so any positive

types can take it!

• Can Receive From:– Type O and O+

(7) Type AB• Antigens = A and B

• Antibodies = Rh

• Can Donate To:– Type AB– Type AB+

• Can Receive From:– Type A– Type B– Type AB– Type O

(8) Type AB Positive• Antigens = A, B and Rh

• Antibodies = None

• Can Donate To:– Only Type AB+

• Can Receive From:– Type A and A+– Type B and B+– Type AB and AB+– Type O and O+

(9) Type A• Antigens = Only A

• Antibodies = B and Rh

• Can Donate To:– Type A and A+– Type AB and AB+

• Can Receive From:– Type A– Type O

(10) Type A Positive• Antigens = A Rh

• Antibodies = B

• Can Donate To:– Type A+– Type AB+

• Can Receive From:– Type A and Type A+– Type O and Type O+

(11) Type B• Antigens = Only B

• Antibodies = A and Rh

• Can Donate To:– Type B and B+– Type AB and AB+

• Can Receive From:– Type B– Type O

(12) Type B Positive• Antigens = B and Rh

• Antibodies = A

• Can Donate To:– Type B+– Type AB+

• Can Receive From:– Type B and B+– Type O and O+
