Presentation Transcript

Components of blood
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
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
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
Group A blood

  • A antigens on the surface of your RBCs

  • B antibodies in your blood plasma


Group b blood
Group B blood

  • B antigens on the surface of your RBCs

  • A antibodies in your blood plasma


Group ab blood
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
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 Factors

  • Rh+

    • Protein found in blood

    • Can receive Rh+ or Rh- blood

  • Rh-

    • Lack protein in blood

    • Only receive Rh- blood

  • Acceptor

    O-

  • Donor

  • AB-

No! The AB antibodies

attack the donors blood.

Blood type O can only receive

Blood type O.

  • A-

Yes! There are no Rh antigens

on the donors blood cells.

    AB-

  • Donor

  • B-

Yes! The AB patients can receive

any blood type. And, both people

do not have Rh antibodies.


White blood cells
White Blood Cells

  • Remove foreign invaders & dead cells

  • Able to move through body tissue


Platelets
Platelets

  • Form clots when bleeding

  • Proteins form a web to trap cells & platelets
