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.
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
Definition: the right upper chamber of the heart that receives blood from the venae cavae and coronary sinus
The left ventricle receives oxygen from the chest. The right ventricle receives oxygen from the rest of the body. PS..... Ur Welcome :)
There are definitely three chambers in a frog's heart - the left atrium, right atrium, and the ventricle. There is only 1 ventricle in a frog's heart, unlike the humans, with 2 separate ventricles for oxygenated and deoxygenated blood. In a frog, the blood mixes together in the ventricle.
Circulatory system
It is for your mom
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.
right atrium
the size of the right atrium is smaller that the left atrium.
The cranial and caudal vena cava open in the right atrium.
