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.

Identify and describe the features of Rotifera and Acanthocephala that make them distinct from one another, and how is the ‘relatedness’ of these organisms supported by molecular data? Identify two specific anatomical features of free-living and parasitic flatworms and relate it to their mode of living.

What type of symmetry is seen in the roundworm? Does it exhibit cephalization? Ascaris is a parasite that swims constantly in human intestines. What structure protects the nematode from being digested? View the Trichinella slide. Trichinella is also a parasite. It can infect humans as well as other mammals like pigs, bears, and rodents. If untreated, it can lead to death.What mammal tissue does this roundworm infect?Draw a picture below of the Trichinella as viewed under the microscope.
