The digestive system is actually a long hollow tube called the gastrointestinal tract, or GI tract. The digestive system includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine.Several major glands include the salivary glands, the pancreas, and the liver.

The mouth is the organ in which the process of digestion begins.he first task of the digestive system is to break down food into a fine pulp (mechanical digestion).
