How does your body kill germs inside your body?

The body employs the immune system to kill germs, utilizing various components such as white blood cells, antibodies, and other immune cells. When pathogens enter the body, immune cells like macrophages and neutrophils identify and engulf them. B cells produce antibodies that specifically target and neutralize these invaders, while T cells can directly kill infected cells or help coordinate the immune response. Additionally, inflammation and fever can enhance the body's ability to fight off infections.
