What makes our blood different from others

BLOOD TYPES

ABO SYSTEM BLOOD TYPES
MICROSCOPIC MARKERS (ANTIGENS) MAKES ONE BLOOD TYPE DIFFER FROM ANOTHER
OUR BODY USES ANTIGENS TO KNOW IF THE BLOOD CELL OURS OR NOT

THERE ARE 4 MAIN BLOOD GROUP

RH FACTOR
SOME PEOPLE HAVE ANOTHER MARKER ON THEIR RED BLOOD CELL
MARKER D OR RH FACTOR
PEOPLE WHO HAVE THE RH FACTOR ARE RH-POSITIVE
PEOPLE WHO DON’T HAVE THE RH FACTOR ARE RH-NEGATIVE

BLOOD TRANSFUSION
IF A PATIENT WITH A BLOOD TYPE IS GIVEN B BLOOD TYPE, PATIENT IMMUNE SYSTEM WILL RECOGNIZE B BLOOD AS ENEMY, AND PRODUCE ANTIBODIES AGAINST B ANTIGENS
THIS PROCESS CAUSES AGGLUTINATION OF RED BLOOD CELLS
AGGLUTINATION CAN BLOCK BLOOD VESSELS, AND THIS LEADS TO ORGAN DAMAGE OR DEATH
