Digestive system

• The digestive system is a group of organs that break down food, absorb nutrients, and remove waste.
• It includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
• • The liver and pancreas play key roles in digestion.
• Digestion begins in the mouth with chewing and the action of salivary enzymes.
• • Food travels down the esophagus into the stomach, where it is broken down by stomach acid.
• • The food then moves into the small intestine, where most nutrient absorption occurs.
• • Remaining waste travels to the large intestine, where water is absorbed.
• • Leftover waste is excreted from the body.
