Miraculously, our body can heal itself and the healing process is still going on while you are sitting and reading this. If you are affected by a cut or infection or even if a disease, the virus or allergen finds a way to enter your body.
To this action, your immune system reacts by sending specialized white blood cells directly to the affected area. These white blood cells help in repairing the damage caused by the infection and even stop the spread of infection and illness. Whereas, in some cases, it even eradicated the intruder. This whole process and response are called inflammation.
