answer:The digestive system has four phases: ingestion, digestion, absorption, and elimination. Ingestion involves taking food into the mouth and breaking it down into smaller pieces by chewing and mixing it with saliva. Digestion includes mechanical and chemical processes. In the stomach, muscles contract to mix food with hydrochloric acid and enzymes to break it down further. In the small intestine, enzymes from the pancreas, liver, and small intestine itself, break down proteins, carbohydrates, and fats so they can be absorbed. Absorption occurs in the small intestine, where nutrients and water are absorbed into the bloodstream and transported to the liver. Elimination is the process of excreting waste products from the body through bowel movements. Waste products include indigestible food, fiber, and dead cells.
