Question

How do flatworms remove waste?

Answer 1

Excretion in flatworms:

1. Flatworms fall under the phylum Platyhelminthes.
2. Platyhelminthes is another term used for flatworms.
3. Flatworms breathe through the skin.
4. They have bilateral symmetry in their body structure.
5. A specialized respiratory system, skeleton system, circulatory system, or complex reproductive system seem to be absent in Platyhelminthes.
6. Hence, they are soft-bodied invertebrates.
7. Platyhelminthes have specialized cells known as flame cells that assist in removing waste from their bodies.
8. The flame cells are excretory cells attached with ciliary (hair-like) cells that move the waster material from the tubes to out of the body.
9. Protonephridia is the term called for bundles of flame cells.
