gill filaments function

Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Some species of sharks that aren't active swimmers can switch between ram breathing and other methods of moving water over the gills or use other methods completely. Gill filaments are the red, fleshy part of the gills; they take oxygen into the blood. So, as you can see, gills are all around us in the animal kingdom. It also ensures that a favourable diffusion gradient is maintained. the efficient ventilation of the gills with water there is a counter current flow of water and blood. These organ typically use a chemical process to extract oxygen from the water, rather than using gills like fish do. What is the function of the gill filaments?
