In this video Dr. Priyanka Dadupanthi, Asst. Professor, Biyani Girls College is explaining about the Flame cells or protonephridia which are the important part of protonephridial system. This system is concerened with excretion and osmoregulation in Platyhelminths (Fasicola hepatica). These are arising from basal granules. The term “flame” is due to vibrant like flickering of these structures. Excretory products diffuse into flame cells. From mesenchyme of these cells these products are pushed into longitudinal excretory canal and finally pushed outside by excretory pore.
