The human digestive system is a complex network of organs and processes designed to break down food, absorb nutrients, and expel waste. This system involves mechanical and chemical processes that work together to ensure the body receives the necessary nutrients for energy, growth, and cellular repair.

The human digestive system is a highly coordinated network involving mechanical and chemical processes to break down food, absorb nutrients, and expel waste. Key components include the stomach's role in acid and enzyme secretion, the small intestine's function in nutrient absorption, and the liver's role in nutrient processing. The gut microbiota significantly influences digestion and health, while neural and hormonal systems regulate digestive functions and gastrointestinal motility. Together, these elements ensure the efficient processing and utilization of food for the body's needs.
