The excretory structures of terrestrial arthropods are slender projections from the digestive tract called malpighian tubules.
What are Malpighian tubules?
The malpighian tubules are channels in the digestive system of the alimentary canals present in arthropod species.
The Malpighian tubules function to provide an excretory system and osmo-regulatory system to arthropods.
These slender tubules are fundamental for the survival of many species of insects (i.e., arthropods).
