2. Digestion starts at the mouth, it is where they are chewed or swallowed. Food then passes through at the esophagus. Food reaches the stomach, the food mixes up with the digestive juice produced by the stomach. Stomach empties its content to the small intestine.
3.The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
