Components of Blood • Whole blood • RBCs • WBCs • Platelets: cell fragments that aid in clotting • Plasma • 90% water (allows materials to dissolve) • Amino acids, glucose, hormones, vitamins, salts, waste • Concentrations allows diffusion in/out of blood stream
Red Blood Cells • Produced from stem cells in bone marrow • Lose nucleus as they mature • Transport O2 to cells; remove CO2 • O2 binds to hemoglobin proteins • Dead cells filtered by liver & spleen
Sickle Cell Normal
ABO Blood Groups • Proteins on blood cells determined blood type • Antigen (markers) • proteins on cell’s surface that identify cells as foreign or natural • Antibodies: • proteins from WBCs to attack invaders • Float freely in plasma
Group A blood • A antigens on the surface of your RBCs • B antibodies in your blood plasma
Group B blood • B antigens on the surface of your RBCs • A antibodies in your blood plasma
Group AB blood • A and B antigens on the surface of your RBCs • no A or B antibodies at all in your blood plasma
Group O blood • No A or B antigens on the surface of your RBCs • both A and B antibodies in your blood plasma
Rh Factors • Rh+ • Protein found in blood • Can receive Rh+ or Rh- blood • Rh- • Lack protein in blood • Only receive Rh- blood
1) Can this work? • Acceptor O- • Donor • AB-
2) Can this work? • Acceptor A+ • Donor • A-
3) Can this work? • Acceptor AB- • Donor • B-
1) Can this work? • Acceptor O- • Donor • AB- No! The AB antibodies attack the donors blood. Blood type O can only receive Blood type O.
2) Can this work? • Acceptor A+ • Donor • A- Yes! There are no Rh antigens on the donors blood cells.
3) Can this work? • Acceptor AB- • Donor • B- Yes! The AB patients can receive any blood type. And, both people do not have Rh antibodies.
White Blood Cells • Remove foreign invaders & dead cells • Able to move through body tissue
Platelets • Form clots when bleeding • Proteins form a web to trap cells & platelets
