3. The Stomach
This is a J-shaped, muscular bag. When it's empty, it's quite small, but it stretches to hold your food.
Its job is to:
Churn and mix the food with strong acid and more enzymes, turning it all into a soupy mush.
💡 Fun Facts
- The acid in your stomach is strong enough to dissolve some metals!
- Don't worry, your stomach is protected from its own acid by a thick layer of slimy mucus.
- Your stomach 'growls' when you're hungry because it's squeezing air and any leftover bits around.
