Have you ever wondered what makes you... well, Sure, you’ve got skin, bones, and muscles, but have you ever thought about what those are made of? Let’s shrink down, way down, and discover the building blocks that make up every part of us!

Imagine using a magical microscope to zoom into the human body. If we zoom into any living creature, guess what we find? We’re all made of cells! But before we dive deeper into cells, click on "live" to learn what it means for something to be a living organism.

Now, back to cells! We’re made up of trillions of them. Cells are the smallest units of life in our bodies, like tiny factories with different departments, each doing its own job. Just like a factory imports and exports goods, cells handle all sorts of tasks to keep everything running smoothly.

In fact, just one drop of blood or a tiny piece of skin contains millions of these little powerhouses, all working hard to keep us alive.
