Directions
The foods we eat contain nutrients, but we need to break down the foods first to get to those nutrients. Sometimes we need to break down the nutrients even further so they can be easily transported to all our cells. This is what the digestive system is for.
The digestion of sugars and starches starts in the mouth, the moment we start salivating and chewing. We break down the carbs further in the stomach. Finally, the nutrients travel through the small intestine where they pass into the bloodstream and are absorbed by our cells.
