Do Frogs have a double circulatory system?

As such, amphibians have a double circulatory system composed of two circuits. The systemic circuit circulates blood between the heart and the rest of the body, and the pulmocutaneous circuit circulates blood between the heart and the lungs and skin.

How does blood circulate through a frog?

In the frog, Rana, venous blood is driven into the right atrium of the heart by contraction of the sinus venosus, and it flows into the left atrium from the lungs. A wave of contraction then spreads over the whole atrium and drives blood into the ventricle, where blood from the two sources tends to remain separate.

Do amphibians have a double circulatory system?

Amphibians have a three-chambered heart – two atria and one ventricle. The mixing of oxygenated and deoxygenated blood is kept to a minimum due to the timing of the contractions between the atria. This is called an incomplete double circulatory system.
