Human Body: Digestive System

Dr. Forrester introduces the digestive system, explaining how it breaks down food into nutrients. The process begins in the mouth, where saliva and teeth start digestion. Food travels down the esophagus to the stomach, where gastric juices further break it down. Nutrients are absorbed in the small intestine, aided by the liver and pancreas. The large intestine handles waste removal, with kidneys filtering liquid waste. The digestive system is a complex and efficient system.
