Journey Through the Digestive System

The video tutorial explores the digestive system, starting from the mouth where digestion begins with saliva and enzymes. It then moves to the stomach, where gastric juices further break down food. The journey continues to the small intestine, where nutrients are absorbed with the help of bile and enzymes. Finally, the large intestine absorbs water and forms waste. The tutorial provides a comprehensive overview of how the body processes food into energy and waste.
