What is immune system?
The immune system is a whole network of cells, tissues and organs, they work together to defend the foreign invaders. Those cells are involved in white blood cells, or leukocytes and so on. They focus on protecting your body from being attacked by millions of virus, bacteria, germs, toxins and parasites. Before knowing how it works, you should know what would happen if you lose it first.
When the living beings die,the system will stop working. What the consequences? The body will be invaded by the bacteria, germs and parasites after the system terminate their activities.
However, all those bad things can’t intrude as the system works normally. The consequences of invasive things, the body will be collapsed completely until nothing’s left. This is the purpose of our system.
Our immune system is complicated as well as interesting. It works day and night and being overlooked in most of time by most of us. One condition can draw our attention, that is, we will notice the abnormality of your system as it is disturbed. For example, when your finger is cut and then various viruses and germs access into your body, after that, it responds to that and heals your finger all by itself. Sometimes, the system will make mistakes, triggering the inflammation of the wound. Pustule and inflammation are all the side-effects coming from it.
The immune system will bring troubles as it fail to function. The consequences are various diseases. This is called autoimmune disorder. Normally speaking, the allergy is kind of over-reactive reactions. One more example, diabetes is caused by abnormal immunity and it attacks and destroys pancreas cells.
More often than that, this system will hold back some of our actions which is beneficial for us. For example, organ transplant is much harder than we thought, this is just because our own immune system resist the transplantation.
