Our immune structure is vital for our survival, without it, our bodies would be open to outbreak from bacteria, viruses, parasites, and other foreign particles. So, it is only immune system that keeps us strong in this environment that is full of pathogens. The immune system is a complex web of cells and proteins that protects the body from any infection. This huge network of cells and tissues is continuously on the viewpoint for attackers i.e. all pathogens and foreign particle, and once an enemy is marked, a composite attack is mounted by the immune system. The immune system saves a record of each germ (microbe) it has ever overcome so it can recognize and destroy the microbe quickly if it enters the body again.
