The conventional life cycle of a pink blood cell consists of manufacturing within the bone marrow after which launch into the bloodstream. After a pink blood cell has served its objective, the physique naturally breaks it up and disposes of it. Completely different components of the pink blood cell are circulated by the spleen, liver, and bone marrow and both recycled or destroyed. Particularly, the liver recycles the iron portion of a pink blood cell referred to as bilirubin. These physique programs work to repeatedly preserve outdated pink blood cells damaged down, their elements both used/recycled or disposed of, all whereas pumping out new pink blood cells from the bone marrow to maintain the physique’s circulatory system balanced.
If the immune system is triggered by one thing (mentioned extra under), then the pink blood cells are “marked” for destruction. This may increasingly not sound like a giant deal, however it will possibly turn out to be essential if the physique is unable to maintain up with an ample manufacturing charge of pink blood cells to offset the quantity being destroyed. Each the liver and spleen will turn out to be overwhelmed with the variety of pink blood cells and pink blood cell “items” to course of, inflicting points in these respective organs. As well as, all the pink blood cells will turn out to be marked and/or coated with antibodies. These antibodies will trigger pink blood cells to stay collectively, inflicting probably deadly blood clots. The antibodies additionally set off different programs within the physique to additional destroy them. All in all, it’s a vicious cycle.
