When you bite into an apple, it embarks on a long journey: digestion.
👄 The mouth
The teeth grind the food, and saliva begins to break it down.
🫣 The stomach
It churns and mixes the food with digestive juices, turning it into a kind of mush.
🌀 The small intestine
About 6 to 7 meters long, it absorbs nutrients into the bloodstream, which carries them to the entire body.
🚽 The large intestine
It absorbs water and eliminates waste.
🧪 Experiment: chew a piece of bread for 2 minutes without swallowing it: it becomes sweet! Saliva turns the starch into sugar. See the pocket microscope
