Question

Which organ allows flatworms to excrete waste materials from their bodies?

Answer 1

Hint: Flatworms that live in the wild are predators or scavengers, whereas parasitic flatworms feed on their hosts' tissues. The digestive system of most flatworms is incomplete, having an aperture called the "mouth" that is also utilised to remove digestive system wastes. Anal openings can also be found in some animals.

Complete answer:
The flatworm's body contains a large number of flame cells that perform excretion functions. Protonephridia is another name for flame cells. Each flame cell pulls excretory fluid, which is then sent through a tubular network.

Flatworms, commonly known as platyhelminthes, are invertebrates. Their bodies are soft and flattened. Flatworms are generally parasitic, which means they survive by living inside or on top of another organism. Flatworms can also live on their own.

Flatworms, or the phylum Platyhelminthes, are being reorganised, and the descriptions here will follow the usual categories. The majority of flatworms are parasitic, including important human parasites.

Flatworms have three embryonic germ layers that give rise to the surfaces that cover tissues, internal tissues, and the digestive system's lining. A single layer of cells or a layer of fused cells covers a layer of circular muscle on top of a layer of longitudinal muscle in the epidermal tissue. Support cells and secretory cells produce mucus and other materials to the surface of the mesodermal tissues.

Note:
Turbellaria, Monogenea, Trematoda, and Cestoda are the four conventional classifications for flatworms. Turbellarians are mostly free-living marine species, but some live in freshwater or moist terrestrial habitats. Simple planarians can be found in freshwater ponds and aquariums.
