What is the function of the digestive system?

The digestive system is responsible for breaking down food into nutrients that the body can absorb and use for energy, growth, and repair. It includes organs such as the mouth, oesophagus, stomach, intestines, liver, and pancreas. The process begins with chewing in the mouth, where enzymes in saliva start breaking down carbohydrates. In the stomach, acids and enzymes further digest food. The small intestine absorbs nutrients, while the large intestine processes waste. The digestive system also regulates hydration and maintains a balance of beneficial bacteria.
