Digestive System Functions and Processes

The video explains the human digestive system, starting from the mouth where food is cut and mixed with saliva. It then moves to the esophagus, where food is pushed to the stomach. The stomach stores, mixes, and processes food with enzymes and acids before passing it to the small intestine. Here, nutrients are absorbed with the help of enzymes and bile. The remaining waste moves to the large intestine, where water and minerals are absorbed, and waste is expelled. The video concludes with a call to action for viewers to visit a website and engage with the content.
