Autoimmune diseases are those that involve the immune system functioning erroneously, such as when the body mistakes its own healthy cells as invaders.
The immune system is a advanced network of organs, cells and proteins that defends the body against infection, while protective the body's own cells. The system keeps a record of each germ (microbe) it's ever defeated thus it will recognise and destroy the germ quickly if it enters the body once more.
Autoimmune disease happens once the body's natural munition cannot tell the distinction between your own cells and foreign cells, inflicting the body to erroneously attack traditional cells. There are quite eighty varieties of reaction diseases that have an effect on a large vary of body components.
