Imagine you're a tiny explorer, ready to journey through the human digestive system. Your adventure starts in the mouth, where teeth grind you up, and saliva begins breaking you down. Sliding down the esophagus, you land in the stomach.
Here, powerful acids dissolve you further. Next stop, the small intestine! Nutrients get absorbed here, helping the body grow and repair. The leftover waste then reaches the large intestine, where water is absorbed, and the remaining waste is excreted. Did you know? This whole system, if stretched out, is as long as a double-decker bus!
