The digestive tract performs several essential functions, including the mechanical and chemical breakdown of food, nutrient absorption, and waste elimination. It begins with ingestion, where food is taken in, followed by digestion in the stomach and small intestine, where enzymes and acids further break down food. Nutrients are then absorbed through the intestinal walls into the bloodstream, while indigestible parts are prepared for excretion through the large intestine. Overall, the digestive tract ensures that the body obtains the necessary nutrients to function properly.

The vagus nerve also helps regulate heart rate and other involuntary functions, linking the brain to the digestive organs.
