EACH BLOOD TYPE IS NAMED

ACCORDING TO THE ANTIGENS

ON ITS SURFACE


EACH BLOOD TYPE

PRODUCES ANTIBODIES

AGAINST ANY ANTIGEN

IT DOES NOT POSSESS –

ANTIGEN

THAT IS FOREIGN


WHEN INCOMPATIBLE

BLOOD TYPES ARE

MIXED, A DANGEROUS

CONDITION RESULTS

CALLED

AGGLUTINATION


THERE ARE THREE

MAJOR ANTIGENS

ON THE SURFACE OF

RED BLOOD CELLS

- B ANTIGEN

RH ANTIGEN


LIKEWISE THERE ARE

THREE IMPORTANT

ANTIBODY TYPES

PRODUCED AGAINST

EACH OF THE THREE

ANTIGENS


Antibodies
ANTIBODIES

ANTI - A

ANTI - B

ANTI - RH


Type a blood
TYPE A- BLOOD

  • CONTAINS A ANTIGEN

  • MAKES ANTIBODIES AGAINST B BLOOD – ANTI-B & RH FACTOR


Type b blood
TYPE B+ BLOOD

  • MAKES B ANTIGEN

  • MAKES RH ANTIGEN

  • MAKES ANTIBODIES AGAINST A BLOOD – ANTI -A


Type ab blood
TYPE AB- BLOOD

  • CONTAINS BOTH A AND B ANTIGENS

  • MAKES NEITHER ANTI-A OR ANTI-B BOTH ARE SELF PROTEINS

  • MAKES ANTI –RH ANTIBODIES


Type o blood
TYPE O- BLOOD

  • CONTAINS NEITHER A NOR B NOR RH ANTIGENS

  • MAKES ANTI-A AND ANTI-B AND ANTI –RH ANTIBODIES


Type a blood1
TYPE A+ BLOOD
