Excretory Structures in Animals -

  • Protonephridia or flame cells are the excretory structures in Platyhelminthes (Flatworms, e.g., Planaria), rotifers, some annelids and the cephalochordate – Amphioxus.
  • Protonephridia are primarily concerned with ionic and fluid volume regulation, i.e., osmoregulation. 
  • Nephridia are the tubular excretory structures of earthworms and other annelids.
  • Nephridia help to remove nitrogenous wastes and maintain a fluid and ionic balance. 
  • Malpighian tubules are the excretory structures of most of the insects including cockroaches. 
  • Malpighian tubules help in the removal of nitrogenous wastes and osmoregulation.
