Food's incredible journey

The video explains the journey of food through the human digestive system. It starts with the intake of food, which is chewed and mixed with enzymes in the mouth. The food then travels down the esophagus to the stomach, where it is further broken down by acids and enzymes. Nutrients are released and absorbed in the intestines, entering the bloodstream to nourish the body. The process ensures we receive essential nutrients for energy, growth, and health.
