Fishes use gills for respiration purposes. The gills remain covered by flaps. The fish opens the flaps to allow the water to reach the gills.
The water contains dissolved oxygen in it that the gills absorb during the respiration process.
During the respiration process, the water and blood flow directions are opposite across the gills.
