What is the excretion of platyhelminthes?

Answer 1

Platyhelminthes, or flatworms, excrete waste primarily through a network of flame cells and tubules that form a protonephridial system. This system functions by filtering body fluids and removing nitrogenous wastes, which are then expelled through excretory pores. Additionally, they can also excrete waste products through their body surface via diffusion. This efficient system allows them to maintain osmotic balance in their aquatic environments.
