- Additional information
The heart of the frog has three chambers, one ventricle and two atria. The atrium receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin, which also serves as a gas exchange organ in most amphibians, and then both atria empty into the single ventricle. While this might appear to now allow oxygenated and deoxygenated blood to be kept separate, the ventricle is divided into narrow chambers that reduce the mixing of the two types of blood.
