Concept:
- Excretion is the process of removal of nitrogenous wastes from the body of an organism.
- Excretion is performed by a specialized group of cells or organs called excretory organs.
- Different organisms have a different type of excretory organs
- Example: 1) Flatworms – Protonephridia & flame cells, 2) Earthworms – Nephridia, 3) Insects – Malpighian tubules, 4) crustaceans – green glands, 5) All chordates - Kidneys
Explanation
- The malpighian tubule is the excretory organ of the phylum Arthropoda (Insects).

- In insects, a malpighian tubule is present in the abdominal cavity
Additional Information
Different organisms use different types of organs to remove excreta.
- Unicellular Animals / Amoeba – Diffusion through the surface of the body.
- Platyhelminthes/ Flatworms – Flame cells
- Roundworms/Earthworms – Nephridia
- Arthropods/ Cockroaches – Malpighian tubules
- Crustaceans / Prawns – Antennal glands / Green Glands
- Vertebrates – Kidney
