In school we were taught different parts and different organs of our bodies have their own function and roles. The heart pumps the blood, the kidneys takes out the waste and this continuous. But what if I tell you that it's actually the bones that make blood in our bodies?
Would you believe that? This is Now You Know and in today's video we will tell you about how the bones in our bodies make blood.
Millions of blood cells are flowing throughout our body each of these having its origin deep inside our bone. Yes you heard it right Bones. The bones seems strong but they are quiet porous inside and large and small blood vessels enters through these holes and inside those large bones there is a hollow space filled with soft bone marrow.
Marrow contains fats and blood stem cells, these cells are constantly dividing which future makes Red blood cells, white blood cells and even platelets and sends billions of these new cells into circulation every day.
If there is a problem with your blood then it might be traced back to your marrow. If someone is facing blood cancer the only way to solve is to transplant bone marrow.
Fresh stem cells are taken from the donor's marrow and while all this happens the marrow present in the patients is killed by sending high chemo radiation this also makes the patient immune system week.
Later the fresh stem cells are injected in the patients through a central line. The cells quickly travel back to the bone marrow where it can divide itself and can get back to its work.
It is very important that the donors and recipients have the same DNA composition this helps the immune system to accept the foreign substance. Because these genes are inherit the best possible match is off a sibling.
