The flame cell has a nucleated cell body, with a "cup-shaped" projection, with flagellacovering the inner surface of the cup. The beating of these flagella resemble a flame, giving the cell its name. The cup is attached to a tube cell, whose inner surface is also coated in cilia, which help to move liquid through the tube cell. The tube opens externally through a nephropore, or, in the trematoda, into an excretory bladder. The function of these cells is to regulate the osmotic pressure of the worm, and maintain its ionic balance. Microvilli in the tube cell may be used to reabsorb some ions.[1].
Flame cells and nephridia: In the excretory system of the (a) planaria, cilia of flame cells propel waste through a tubule formed by a tube cell. In (b) annelids, nephridia filter fluid from the body cavity
