1. The Mouth
This is where the journey begins! Your teeth, tongue, and saliva all work together.
Its job is to:
Grind, chop, and mash the food (mechanical digestion) and mix it with saliva. Saliva has special chemicals (enzymes) that start breaking down the food (chemical digestion).
💡 Fun Facts
- You make about 1 to 2 litres of saliva (spit) every single day. That's enough to fill a big bottle of lemonade!
- Your tongue is a super-strong muscle that pushes the food around your mouth and helps you swallow.
- Chewing your food properly makes the rest of the journey much easier for your digestive system.
