What is the difference between a complete digestive system and an incomplete digestive system? Extracellular digestion takes place within the central cavity. How do the two systems differ? A complete digestive system absorbs nutrients better because each organ is different and can specialize. A complete Microscopic images, SDSPAGE, lipolysis rate and bioaccessibility were used to discuss the in vitro . Complete digestive systems are more complex and have a complete tube with separate openings for food and waste. Unlike some animals (like the starfish) where intake and output occur in the same place, a complete digestive tract is one where food travels one way only.
