A flame cell is a specialized excretory cell found in simple invertebrates, including flatworms (Platyhelminthes), rotifers and nemerteans; these are the simplest animals to have a dedicated excretory system. Flame cells function like a kidney, removing waste materials. Bundles of flame cells are called protonephridia. [1]
The tube cells' flagella drive the water towards exits called nephridiopores, while their microvilli reabsorb reusable materials and as much water as is needed to keep the body fluids at the right concentration. These combinations of flame cells and tube cells are called protonephridia. [5] [15]
In biology, solenocytes are elongated, flagellated cells commonly found in lower invertebrates, such as flatworms (phylum Platyhelminthes), chordates (sub-phylum Cephalochordata) and several other animal species. [citation needed] In terms of function, solenocytes play a significant role in the excretory systems of their host organism(s). [1]
Also, flame cells remove unwanted liquids from the body by passing them through ducts which lead to excretory pores, where waste is released on the dorsal surface of the planarian. The triclads have an anterior end or head where sense organs, such as eyes and chemoreceptors , are usually found.
Flatworm flame cell. A protonephridium (proto = "first") is found in the phyla Platyhelminthes, Nemertea, Rotifera and Chordata . They have the same anatomy as the metanephridia but with the internal ciliated funnel blocked by terminal cells: either a flame cells (if ciliated) or a solenocytes (if flagellated).
Many flatworms are considered invasive pests, since they eat native earthworms, snails and other soil organisms. And like other worms, they can reproduce asexually − even being split in half − ...
Each proglottid contains an independent reproductive tract, and like some other flatworms, cestodes excrete waste through flame cells (protonephridia) located in the proglottids. The sum of the proglottids is called a strobila, which is thin and resembles a strip of tape; from this is derived the common name "tapeworm".
A parasite called Heterobilharzia americana, a flatworm commonly referred to as liver fluke, was behind the illness of the 11 dogs. The parasite normally makes its home in Texas and in the South.
