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.
The Deoxygenated blood flows from the body into the right atrium. Oxygenated blood from the lungs flows into the left atrium. Since frogs have only one ventricle, the oxygenated and deoxygenated blood mixes in the ventricle. From there, blood flows into the truncus arteriosus that contains a spiral valve to separate and lead the blood out into the body.
It has 4 chambers so oxygenated blood from the lungs never mixes with deoxygenated blood from body tissues as it does in frogs that have only 3 chambers.
right atrium,right ventricle,left atrium and left ventricle.

There are two atria and one ventricle. The two atria are fed from the body and the lungs. The single ventricle pumps into both the body and the lungs. Blood mixes in the ventricle.
I believe that the frog heart has one large chamber. When the "dirty" blood returns to the heart from nourishing the body, it mixes with the newly oxygenated blood from when the frog breathed. This type of heart is not as efficient as other animals with chambers to keep the two kinds of blood "dirty" and oxygenated separated. The frog still gets rid of waste gas and pumps fresh gas to its body but some of the waste blood gets pushed around the body too. The frog blood contains a lower concentration of pure gas blood than other animals.
the ice will melt
the quality of our blood that rich with oxygen will become low
it will cross the water
Gas molecules are moving and mixing of.
Blood has different mixes which makes some blood different from others this is very important during blood transfusions.
