The Microbial City Within You

You are more microbe than human. The trillions of microbes living in your body actually

outnumber your own cells. But your 40 trillion human cells are the real MVPs.

Each one is a bustling mini-city. The nucleus is city hall, holding all the

DNA blueprints. The mitochondria are the power plants, cranking out energy 24/7 so you can

live. The cell membrane is the bouncer, deciding who gets in.

And get this—cells have their own stomachs. They’re called lysosomes, and they're little sacs of digestive

enzymes that break down invaders and recycle old parts. All these tiny cities work together to

create you.
