Question

discuss respiration in relation to gills

Answer 1

Answer:

Gills are the respiratory organ which is found in many aquatic species including mollusks, all fishes, and a few amphibians.

The gill has filament of branched tissue which is supplied with blood vessels.Near the surface of gills, the exchange of oxygen and carbon dioxide occurs.

Gills help the organism to respire underwater.Mostly the respiratory process involves exchange of gases like oxygen and carbon dioxide using gills that are protected under pharynx (throat).

Fillaments in the gills does many functions,which is involved in transfer of ions and water, and exchange acids ,ammonia, oxygen, carbon dioxide, acids and ammonia.

The organisms with gill exchange gases by consuming water which is rich in oxygen through their mouths and transfer it to their gills. And then gills push the water which has poor oxygen water out via pharynx.

After the water passes over the gill filaments, capillary blood vessel network collects the oxygen and transport the oxygen through out the body.It picks up carbon dioxide and expels out of the body through operculum in the throat.
