Question

Quizplus · Accepted Answer

Ciliated flame cells are found in the excretory system of planarians and function in the propulsion of fluids, specifically waste and excess water, out of the organism. Earthworms also have excretory systems with flame cells, but they use nephridia instead for fluid transport. Insects and humans have different types of excretory systems without flame cells. Marine fish have kidneys, not flame cells, in their excretory systems.
