What is venous system of frog and how it works?
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.
