The Metropolis Within: Your Cellular City

Your body is a metropolis of trillions of tiny cities called cells. Each cell has its

own power plant, the mitochondria, constantly generating energy. The nucleus acts

as city hall, holding the DNA blueprint for the entire operation. A massive highway

system, the Endoplasmic Reticulum, builds and transports materials,

while the Golgi apparatus acts as the post office, packaging and shipping everything out.

Got waste? The lysosomes are the cleanup crew, recycling old parts and destroying invaders.

All this perfectly coordinated chaos is happening inside you right now. You’re literally

a walking universe of tiny, hardworking cities.
