How Your Immune System Works

N

Neutrophils are the first responders! They rush to the site of infection faster than any other immune cell and attack bacteria directly. They make up about 60% of your white blood cells.

M

Macrophages are the big eaters! Their name means "big eater" in Greek. They engulf and digest germs, dead cells, and debris. They also alert other immune cells to danger.

T

T-Cells coordinate the immune response like generals in an army. Killer T-Cells destroy infected cells, while Helper T-Cells tell other immune cells what to do.

A

Antibodies are Y-shaped proteins that mark invaders for destruction. They stick to germs and slow them down, making it easier for other immune cells to find and destroy them.
