Imagine you're a tiny slice of pizza just starting your journey through the amazing human digestive system, a complex machine around 30 feet long! Your journey starts in the mouth, where teeth crush you, and saliva begins breaking you down.
Swallowed down the esophagus, you land in a pool of stomach acid so strong, it could dissolve metal! Next, it's off to the small intestine, where nutrients are absorbed and sent to cells all over the body. The large intestine then prepares what's left of you for exit, absorbing the remaining water and transforming the waste into solid form.
At the end of your journey, you're expelled from the body as waste. Remember, making this journey smooth requires a balanced diet and plenty of water. So, the next time you enjoy a slice of pizza, think about the incredible journey it takes through the digestive system!
