Amphibians have three heart chambers: two atria and a single ventricle.

  • The atrium receives deoxygenated blood from the blood vessels (veins) that drain the various organs of the body.
  • The left atrium receives oxygenated blood from the lungs and skin (which also serves as a gas exchange organ in most amphibians).
  • Both atria empty into the single ventricle.
