How do they fight the germs?

The body fights germs primarily through the immune system, which includes white blood cells that identify and destroy pathogens. When germs invade, the immune system activates various defenses, such as producing antibodies to neutralize them and deploying phagocytes to engulf and digest the invaders. Additionally, inflammation occurs to isolate and eliminate the infection, while fever can help inhibit germ growth. Overall, this coordinated response helps maintain health and combat infections effectively.
