Q » How does the body fight infections?
06 Dec, 2025
A » The body fights infections primarily through the immune system. When pathogens invade, white blood cells like phagocytes and lymphocytes respond by identifying and eliminating the invaders. Phagocytes engulf and digest foreign particles, while lymphocytes produce antibodies to neutralize specific pathogens. The immune system also remembers past invaders, enabling quicker responses in future encounters. Together, these mechanisms protect the body from infections and maintain health.
