Components of Blood• Whole blood
– Red Blood Cells: Transport O2 to cells
– White Blood Cells: Fight pathogens
– Platelets: aid in clotting
• Plasma– 90% water (solvent)– Solutes: Amino acids,
glucose, hormones, vitamins, salts, waste, antibodies

• Antigens:– Proteins that help
identify cells as foreign or natural
– Found on surface of RBCs• Help to determine
your blood type– Analogy:
Antigens are like jerseys
• Antibodies:– Float freely in
plasma – Attack anything
with foreign antigens
ABO Blood Groups

Group A blood
• RBC’s have the A antigens on their surface• B antibodies in your plasma
– only attack invaders with B antigens
What would happen if a virus with B antigens entered your blood?Your B antibodies will attack and kill this virus.

• RBC’s have the A antigens on their surface• B antibodies in your plasma
– only attack invaders with B antigens
What would happen if you gave this person type B blood?Your B antibodies will attack, and cause clots to form. This person will die.

Rh Factors• If Rh+
– Cells contain the Rh antigen (jersey)
– Blood contains Rh antibody
– Can receive Rh+ or Rh- blood
• If Rh-– Cells lack the Rh
antigen, but…– Blood contains Rh
antibody– Only receive Rh-
blood

1) Can this work?
• Acceptor
O-
• Donor
AB-
No! The acceptor has A & Bantibodies. Their antibodies would attack the A & B antigensof the donated blood.

• Donor
A-
Yes! The acceptor only hasRh antibodies. Since the donatedblood has no Rh antigens, this is safe.

Review1) What are the components found inside blood?
2) What are the ingredients of plasma?
3) What is the purpose/function of RBCs?
4) Which part of blood stop bleeding when cut?
5) What do antibodies bind with?
6) If a person has type AB-, which antigens do they possess? Which antibodies?
7) If a person has type O+, which antigens do they possess? Which antibodies?
8) If a person is type A-, list all the blood types this person can receive in a transfusion.
9) If a person is type O-, list all the blood types this person can receive in a transfusion.
