About Digestive System

The digestive system or alimentary system consists of accessory organs of digestion from mouth to anus along the alimentary canal and gastrointestinal tract. Digestive organs include esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver. Digestive systems’ main function is digestion and absorption of food. The gastrointestinal tract is responsible for mechanical breakdown of food into small molecules that starts in mouth and continues into stomach and chemical digestion by enzymes helps to absorb the nutrients into the body which continues in the intestines.
