Fishes which takes help of gills yo breathe in water, takes water through gills. These gills are made up of capillaries containing blood vessels. These blood vessels absorbs oxygen from water and carry it to the cells.
These tissue also returns CO2 by vessels which is then passes by gills yo the surrounding water.
