The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. WebRespiration in fish or anything living in the water varies from that of human beings. Organisms like fish, existing in water, need oxygen to breathe for cells to endure. Fish has their specific structures to carry out the respiratory purpose, helping them inhale oxygen dissolved in water. WebFish Use Gills To Breathe We get oxygen by filling our lungs with air.
