The Respiration of Gills

Explanation:

  • A primary aspect of aquatic beings such as fish and prawns is their unique breathing organs known as gills.
  • These structures allow for oxygen absorption from water, facilitating gas exchange; the gills are equipped with blood vessels.
  • Amphibians possess gills that enable them to breathe oxygen within the aquatic environment.
  • The gills are located at both sides of the throat, functioning during gas exchange in fish.
  • Gills consist of string-like tissues made of fibrous proteins.
  • These fibers play various roles, including the transfer of ions and water, along with exchanging oxygen, carbon dioxide, acids, and bases.
