Describe the process of respiration in fish.

Respiration in Fish occurs in the following steps:

  • Aquatic animals like fish have specialized organs called gills for breathing.
  • The oxygen dissolved in water is used by the fish for breathing.
  • When the fish takes water in its mouth, it reaches the gills which in turn extract the dissolved oxygen and the remaining amount of water is given out through the slits present in the gills.
  • The blood transports this absorbed oxygen to all parts of the body.
  • The blood also brings back the carbon dioxide from the other body parts which is then expelled through gills to the water present in the surrounding.
