WHY WE NEED IMMUNE SYSTEM
The main tasks of the body’s immune system are:
- to fight disease-causing germs (pathogens) like bacteria, viruses, parasites or fungi, and to remove them from the body,
- to recognize and neutralize harmful substances from the environment in order to limit the extent of their harm if they get into our body
- to fight disease-causing changes in the body, such as cancer cells.
