Function of the Digestive System. The primary function of the digestive system is to break down the food we eat into smaller parts so the body can use them to build and nourish cells and provide energy. The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
The small intestine is the next part of the digestive tract. The small intestine is about 6 meters long, and so it is the longest part of the digestive tract. Its main purpose is the digestion of food and absorption of nutrients.he gall bladder also secretes pancreatic juice and bile into the duodenum. The liver is a very important part of the digestive system, even though food does not directly pass through it. The liver produces bile (a greenish fluid which aids in the digestion of fats), which is stored in the gall bladder.
