The digestive system is a complex network of organs that work together to break down food into nutrients that the body can absorb and use for energy, growth, and repair. It includes the mouth, esophagus, stomach, small intestine, large intestine (colon), liver, pancreas, and gallbladder. Each organ plays a specific role in the digestion and absorption process.

Digestion begins in the mouth, where food is chewed and mixed with saliva containing digestive enzymes. The food then travels down the esophagus to the stomach, where gastric juices break it down further. In the small intestine, nutrients are absorbed into the bloodstream, while the large intestine absorbs water and forms feces for elimination.
