The digestive system breaks down raw food into nutrients, helps prevent harmful substances from entering the body, and removes waste. It includes the mouth, esophagus, stomach, liver, large intestine, rectum, and anus. The mouth chews food and the esophagus transports it to the stomach. The stomach further breaks down food using acids and enzymes before sending it to the small intestine for nutrient absorption. The liver produces sugars and fatty substances while the large intestine collects and moves waste to the rectum and anus for excretion.
