Answer 1

Your white blood cells see it as an invader, something that doesn’t belong. It attacks it viciously as if it were a virus because it doesn’t know better. It kills it and as the organ fails it becomes toxic and it kills you, this isn’t what your body’s immune system wants. It doesn’t know better, it’s programmed that, if this isn’t our hosts e.g. your dna/cells Destroy it. each organ plays a vital role in your survival, you can lose some but others you can’t.
