Explanation:
1. Once filled with food, the stomach grinds the food to break it down into small particles . It then pushes the small particles of food into the first part of the small intestine, called the duodenum. The small intestine is where most of the digestion and absorption of food takes place.
2. The muscles of the small intestine mixes food with digestive juices from the pancreas, liver , and intestine, and pushes the mixture forward for further digestion.
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.
4. The digestive system uses mechanical and chemical methods to break food down into nutrient molecules that can be absorbed into the blood.
