"Googles it"

Frog heart has three chambers.... we have four ...

Both atria (plural for atrium) in a frog function like the atria in the human heart--one receiving oxygenated blood , the other receiving deoxygenated blood. Though rather than the right atrium pumping deoxygenated blood into the right ventricle, and the left atrium pumping oxygenated blood into the left ventricle like in the human heart, both atria empty into the one ventricle in the frog's heart.

There ya go
