Your Immune System’s Hidden War

Your body is currently fighting a biological war you can't even feel. It’s called the

immune system and it operates like a highly trained military unit inside your veins.

You have B cells acting as intel officers, marking enemies with antibodies

so they can be destroyed. Then you have Killer T cells that are straight-up assassins, hunting down infected

cells and taking them out on contact. There are even massive cells called phagocytes that just swallow

invaders whole. The craziest part is that once they beat a virus, they remember it

forever. You are alive right now because millions of tiny soldiers are winning battles

you didn't even know started.
