The digestive apparatus Digestion is a simple process. Large insoluble food particles are broken down into smaller water soluble molecules. So that, they can be absorbed by blood and give energy to different parts of our body. The process of digestion has a few stages: Chewing is the first stage of the digestive system. When you chew your food, the food particles break down into little pieces that are easier to swallow.
