How does your body replenish your blood after it is lost? Is there a certain point where your body is no longer able to make anymore blood?
In: Biology
Blood is made by the soft, fatty marrow inside our bones. It is a slow process for body. Lose too much blood and the body can’t make it fast enough to replace. 40 % loss of blood means some will die. For most adults that is about a half a gallon of blood.
Blood is produced is your bone marrow. There, you have special cells called Hemapoetic Stem Cells which, when they divide, produce one Hemapoetic Stem Cell and one blood cell. It can take days or weeks to fully replenish your blood after you lose a large amount, hence why most blood banks only allow you to donate every couple of months.
If you lose too much blood, your bone marrow can’t keep up and your tissues will start dying as they aren’t getting enough oxygen (with the brain being one of the first to go). In this case you basically experience total system failure and die.
