What is an immune system?

The immune system is a term that describes a biological process in a living organism that protect the organism from any kind of disease or infections. It is a complex combination of various organs, cells and proteins that defends the body against any kind of harm possessed by the outside invader in the body, whilst protecting the body’s own cells.

The immune system is versatile enough to keeps a record of every germ or disease it has ever defeated so that it can recognized and destroyed quickly as soon as it enters the body again. It is the immune system’s job to keep your body healthy. If germs get into your body, it prevents them from entering, kills them, or limits the extent of their damage.  

If we did not have an immune system, we would not be able to fight harmful things entering our bodies or preventing harmful changes from taking place inside, which could be terrible for our body to maintain health.
