Corrected question: Where does digested food turn into poop?
Grammar note: Start the sentence with a capital letter and end with a question mark. You can say either "Where does digested food turn into poop?" or "Where does the digested food turn into poop?" Both are okay.
Simple answer: Most of the change into poop happens in the large intestine (also called the colon).
- Mouth and stomach: Food is chewed and mixed with juices so it breaks into tiny pieces.
- Small intestine: Most nutrients from the food go into your blood here. What is left is mostly water and waste.
- Large intestine (colon): This is where water is taken out of the leftover stuff. As water is removed, the leftover becomes thicker and turns into poop — like squeezing water out of a sponge.
- Rectum: Poop is stored here until you go to the bathroom.
- Anus: This is the exit where poop leaves your body.
It usually takes about one day (sometimes a bit more) for food to travel through the whole system. It is normal and healthy!
