Answer Details
The structure that functions as an excretory system in flatworms is the flame cell. Flame cells are specialized cells that are found in the body of flatworms and are responsible for removing excess water and waste materials from the body. These cells have hair-like structures called cilia that beat in a coordinated manner, creating a current that moves waste materials out of the body. The waste materials are then expelled through pores in the body wall. Therefore, the correct answer is flame cell.
