Only animals with a complete digestive system have evolved specialized organs for digestion. Why? incomplete digestive system (2-way) - This system has a sac-like gastrovascular cavity (GVC) with only one opening to the environment. In this system, food passes through the mouth into the GVC where extracellular and intracellular chemical digestion takes place. The GVC extends throughout the body of the animal so that as food is absorbed it is available to the tissues; no transport system is needed. Waste...
