How does the digestive tract transform food?Food undergoes two kinds of transformation in the digestive tract. Firstly, it is broken down into smaller particles. This is a
mechanical transformation. The ensuing
chemical transformation is more effective on smaller particles than it would be on bigger ones.
Teeth, for example, participate in the
mechanical transformation of food and the stomach’s gastric juices contribute to the
chemical transformation. The chemical transformation is more effective if teeth do their part BEFORE the gastric juices.
