The group of organs and associated structures responsible for digesting food, absorbing nutrients and water, and eliminating undigested waste.
The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus, along with organs such as the liver, pancreas, and gallbladder that contribute to digestion.
Digestion breaks food into smaller components that can be absorbed and used for energy, growth, repair, and other body functions.
QUICK FACT
Most nutrient absorption occurs in the small intestine, not the stomach.
