What is the purpose of the human digestive system?

The human digestive system is responsible for breaking down food into nutrients, which the body absorbs and uses for energy, growth, and repair. The system consists of the mouth, oesophagus, stomach, small intestine, large intestine, and accessory organs like the liver and pancreas. Enzymes and digestive acids help break down carbohydrates, proteins, and fats, while the intestines absorb water and nutrients. Waste products are then eliminated through the rectum. Proper digestion is essential for overall health and well-being.
