The organ system present in free-living flatworms (Turbellaria) and those systems that are absent in (Cestoda) tapeworms. Introduction: Platyhelminthes are soft-bodied invertebrate animals. They have diploblastic organization and acoelomate body plan. They mostly live in aquatic or moist terrestrial habitats. Free-living species consume on prey or decomposing carcasses while the parasitic species consume tissues of living hosts. Platyhelminthes possess bilateral symmetry.

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.
