Life of a Red Blood Cell (RBC)
The RBC lifetime is about 120 days
The life cycle of a Red Blood Cell.
a) Kidneys respond to a lower than normal oxygen concentration in the blood by releasing the hormone erythropoietin.
b) Erythropoietin travels to the red bone marrow and stimulates an increase in the production of red blood cells (RBCs).
c) The red bone marrow manufactures RBCs from stem cells that live inside the marrow.
d) RBCs squeeze through blood vessel membranes to enter the circulation.
e) The heart and lungs work to supply continuous movement and oxygenation of RBCs.
f) Damaged or old RBCs are destroyed primarily by the spleen.
Bombay Blood Types as O
The ONLY True Universal Blood Donor
~ ~ ~
FACTS ABOUT BOMBAY BLOOD:
1. This type is commonly mistaken as type O
2. It can be Rh positive (Rh+) or Rh negative (Rh-)
3. It is lacking the H antigen that we all have
4. ONLY 179 people in India have this type
5. ONLY 4 people in India are reported as having Rh- type of Bombay (hh-)

Understanding The Bombay Blood Group:
When we say someone has blood group A, it means the person has antigen of type A and antibody of type B in their blood. People with AB have both antigen A and B in their blood and no antibodies.
People with O blood group have only antibodies A and B and no antigens.
It is not generally known that all these groups have an H antigen in the blood as well. There are very few people who do not have this antigen H also in their blood. These people are known to have BOMBAY BLOOD.
Why does Bombay Blood Group generally type as O?
Most places where blood type tests are done, the presence & absence of AB and Rh alone is tested in the blood. Bombay Blood Group does not have A or B antigens, it types as O blood. It is only when a specific test for H antigen is done that it can be differentiated between O and Bombay Blood group.
Bombay Blood is the ONLY true Universal Donor…they also can only receive blood from their own type.
