Gas exchange fish
WebThe gas exchange organs of fish are called gills. Fish possess several gills located between their mouth cavity (buccal cavity). Gills of fishes consist of several gill arches on either side. From each gill arch extend two rows of gill filaments. Each filament is covered in lamellae. These further increase the surface area, and because they are ...
