The sound immune system is the key to maintaining good human health. The purpose of this system is to fight the toxic substances including various bacteria, fungi, virus etc.
That’s why people rightly describe human body to be always “at war”. So, to defend against this constant stream of toxins and infections, the immune system comes into 2 broad groups:
- Acquired Immune System
- Innate Immune System
Each of these plays a significant role in promoting good health. However, due to several factors, immunity tends to weaken which led to various diseases and disorders.
