Platyhelminthes are also known as flatworms. They are found in the family planaria and live in ponds while parasitic types such as flukes and tapeworms are found in animal bodies and humans. The phylum Platyhelminthes consist of three different classes: Turbellaria, Cestoda and Trematoda. Planaria- has eyes, auricle, class Turbellaria, lives in fresh water Clonorchis- class Trematoda, parasitic, lives in animal/people Similar- hermaphroditic, phylum Platyhelminthes, gastro-vascular cavity, nerve ladder, flame cells, reproduces sexually & asexually triploblastic 4.

The ‘bladder worms’ typically affect the liver or peritoneal cavity and are caused by the larval form (metacestode) of Taenia hydatigena, the common tapeworm of the dog family. The larval intermediate of another tapeworm of canids, Echinococcus granulosus , also may form hydatid cysts, particularly in liver and lungs. Not all cases are diagnosed because these flukes can be asymptomatic, meaning, they live 25-30 years (or up to 50 years) within your liver, bile ducts or pancreatic ducts and you may never know it. They are often acquired through ingesting fresh water cress, fresh water fish that is raw, pickled, smoked or dried. Students will use whole mount prepared slides of the tapeworm and liver fluke. (Note: These can be purchased through any biological supply house.) They will observe these microscopically and compare them with the planaria. Remind students that both the tapeworm and the liver fluke are parasitic organisms.

Flatworm (Planarian & Tapeworm) Microscope Lab Background In this lab, prepared slides will be used to observe common organisms in the Phylum Platyhelminthes. Flatworms are soft, flattened worms. Flatworms include planarians, flukes, and tapeworms. Objective In this lab, students will observe different body forms in the Phylum Platyhelminthes.

Liver fluke · 3. Tape worm (Taenia solium) Piatyhelminthes (eg, Planaria, liver fluke and tapeworm) possess the simplest tubular excretory systems called protonephridia. A protonephridium is a network of Answer to Phylum Platyhelminthes flatworms: planaria, tapeworms and liver flukes Look at the life cycle of various parasites.

Most flatworms, such as the planarian shown in Figure, have a branching gastrovascular One parasitic group, the tapeworms (cestodes), lacks a digestive system hepatica (two specimens on left, also known as the common liver fluke)

Notably, by contrast, flukes and tapeworms–the Platyhelminths the phylum of relatively simple bilateral, unsegmented, soft- bodied flatworms that include flukes, planaria, and tapeworms. Badge Completion Liver fluke disease (fasciolosis) is caused by the trematode parasite Fasciola hepatica. Disease can result from the migration of large numbers of immature Flatworms (platyhelminths) – these include the trematodes (flukes) and cestodes (tapeworms). Note, however, that in order for humans to become infected with the fish tapeworm, the feces of infected Liver fluke anatomy (a flatworm) 24 Dec 2019 Platyhelminthes are also known as flatworms.

bilateral symmetry Liver flukes are parasites that can infect humans and cause liver and bile duct disease. There are two families of liver flukes that cause disease in humans: Opisthorchiidae (which includes species of Clonorchis and Opisthorchis) and Fasciolidae (which includes species of Fasciola).

2. The hooks attach themselves to the inside of the intestines by hooking in, and the suckers attach themselves to the intestine by suctioning itself to it. 3. Planaria- has eyes, auricle, class Turbellaria, lives in fresh water.

Like all flatworms, planaria belong to the Kingdom Animalia, and the Phylum Platyhelminthes. This phylum also contains parasitic flatworms, like the tapeworm and the liver fluke. Free-living flatworms like the planaria are grouped into the Class Turbellaria. The most common species studied in the lab is the brown planaria, Dugesia.

There are three Classes of flatworms. Class Turbellaria – example Planaria - free living, incomplete gut, no suckers or hooks.

They are acoelomates and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. Planaria, liver fluke, and Taenia all are flat worms. So, the correct answer is option A. Answer verified by Toppr

Learning Objectives. State the phyla of the organisms discussed in the lab activities; Use the characteristics of symmetry, coelom, embryo tissue layers, and patterns of development to differentiate between the different invertebrate groups Fluke (liver, lung, heart, intestine) • Parasitic – Pharynx swallows host’s tissue and body fluids (including blood) – Common intermediate host: raw fish • No need for circulation or respiratory system – Live in tissues supplied by host’s blood – Absorb through gastrovascular cavity • Flame cells • Nerve cords and anterior ganglia – Do not have as specialized nerve cells includes flatworms, flukes, tapeworms in some planarians digestive tract is highly branched to distribute Liver fluke(F. hepatica) → 20,000 eggs/day.

1 Dec 2015 Most eukaryotes including free-living flatworms evolved numerous paralogues of the CYP gene. Notably, by contrast, flukes and tapeworms–the

Planaria are common free living forms, mostly aquatic. The flukes are parasitic in the liver, blood vessels, lungs, bladder, and elsewhere in vertebrate The sheep liver fluke (Fasciola hepatica) is a common parasite of sheep and cattle, which become infected by eating aquatic plants containing encysted metacercariae (juvenile flukes). Humans can acquire the parasite by eating raw watercress (which grows naturally at the edges of lakes and ponds and is cultivated in many countries in Asia and Europe) containing the metacercariae of the fluke. Tapeworms may live in the intestines of almost all vertebrates.
