A » The immune system is your body's defense mechanism against infections. It identifies and attacks pathogens like bacteria and viruses using white blood cells, antibodies, and other defense tools. First, it recognizes the invaders, then it sends out cells to destroy them, and finally, it remembers the pathogens for faster response in the future. Keeping healthy habits supports this amazing protective system!

A »The immune system fights infections through a multi-step process. When a pathogen enters the body, white blood cells called neutrophils and macrophages engulf and destroy it. The immune system also produces antibodies to recognize and bind to specific pathogens, marking them for destruction. For example, when you get vaccinated against flu, your immune system produces antibodies that help fight the flu virus.
