It's a chamber in the heart in which blood flows. It flows through the right atrium and into the right ventricle where it is then pumped into the lungs.
In the leopard frog heart, the right atrium carries oxygen poor blood and the left atrium carries oxygen rich blood.
Definition: the right upper chamber of the heart that receives blood from the venae cavae and coronary sinus
The frog has a three chambered heart, with one atrium and one ventricle.
the heart of a toad is made up of the chambers the left & right atrium and the ventricle

Circulatory system
in comparison to a human heart, a frog heart consists of the right and left atrium, and one large ventricle, while the human heart contains two atrium chambers and two ventricle chambers.

The atrium of a frog is part of the heart and is located on the upper chamber of the heart, also known as the auricle. It receives blood that has circulated through the body and is about to be pumped to the lungs or skin for oxygenation.
the size of the right atrium is smaller that the left atrium.
