Fish remove oxygen from water with specialized respiratory organs called gills. Fish gills are made up of many folds of tissue and are filled with blood.When a fish swims, it takes water in through its mouth and then pushes the water back over its gills. In the gills, oxygen dissolved in the water moves into the fish's blood. Answers taken from 6th grade science book.
